IPhone 3GS GPS

Hi,
The GPS on my iPhone 3GS appeared to stop working. I traveled overseas recently and tried to locate myself with Maps app, and it failed to locate me. (I had cellular off, Wifi ON, LocationServices On, 3G off). The compass app also shows the previous GPS coordinates and never updates to the new location I am in at the moment.
I have tried rebooting my iphone numerous times, resetting network settings, resetting location services, tried different GPS mapping application, tapping the iphone against my hand, standing outside the house hoping to catch any GPS satellites, tried different combination of cellullar/3G/Wifi/LocationServices on/off states, and doing the steps that others suggested (after Google-ing) - all failed to provided me with a working GPS.
If I read "support.apple.com/kb/HT1975" correctly, then when I switch off both cellular and Wifi, iphone 3GS should be using the internal GPS to pinpoint me.
But, according to "support.apple.com/kb/HT1355", the GPS module is switched off if I switch off cellular...which contradicts the KB above..
I tried switch on & off cellular, but my GPS coordinates (as displayed in Compass app) remain wrong. Anyone has similar experience ? Do you think my iphone GPS module is faulty?
Any suggestions would be grateful. Thanks.
Information:
===========================================================================
"support.apple.com/kb/HT1975":
"If you're not within a clear line of sight to a GPS satellite, iPhone 3G and iPhone 3GS find you using Wi-Fi. If you're not in range of a Wi-Fi hotspot, iPhone can find you using cellular towers."
"support.apple.com/kb/HT1355":
"When airplane mode is on, [icon] appears in the status bar at the top of the screen, and no cell phone, radio, or Bluetooth signals are emitted from iPhone (and GPS is not available)."

Same problem here. On a trip abroad the GPS AND Compass completely stopped working. It worked for 7 days abroad before malfunctioning. It has been working flawlessly since I bought it 7 months ago. I´v tried all of the above measures and some more. At times the compass flickers around for a second before locking at Zero degrees North. Maps works as long as i dont try to locate myself. Then the blue haircross-button starts with the "spinning-Wheel" of loading, and just keeps going.
I´ve also noted that since this issue started last week the phone drains the battery a lot faster, even when I´m not fiddling around alot. I did a test some days before this issue and reached 20% in more than 5 days (>120h)!
The only test that I´ve read about and haven´t tested is the "rm -rf"-command witch requires a Jailbraked phone. I argue that I shouldn´t need to jailbrake it to get it to work properly.
So? Is it hardware or software?
Glad for responses.
Wisconxin, did you get it right?

IPhone 3GS GPS no longer working-What should I do?

I have a very annoying problem with my iPhone 3GS.
I have invested a considerable amount of money on Navigation applications and applications that use GPS.
GPS reception started to get unreliable and it was deteriorating over time.
At the beginning my navigation application (Navigon) was losing the GPS signal at random times.
Usually, after every iOS update the GPS reception was fine for a week or so, then problems started again.
Now, GPS is almost not working at all.
All the gps applications on my iPhone can detect where I am, however the precision is in unusable levels. It may show a position 300-400 meters away from where I really am. This happens in Navigon, Maps, etc.
Navigon always shows the red bar on the top telling me that the GPS reception is not adequate.
What should I do? Is there any case that this is a software related issue? Is there any way I can fix this? Some users suggested that I set up as New, but this will be my last resort as I have a lot of data that I want to retain on my iPhone.
Or is this really a hardware issue?
Any suggestions would be highly appreciated.
Thank you

If you've restored the phone and then reinstalled the SW, it may be a HW problem. There's a way to test to see if the GPS is working in 'standalone mode". It's valid for the 3G, I think it works for the 3GS as well.
On the 3G, the GPS receiver is tied to the cellular transceivers. If it's in Airplane mode the GPS doesn't work. Taking the phone out of Airplane mode, but removing the SIM card (and therefore no cellular connection) it works just fine (OK, it's a bit slower, but it still works).
As a final test, take the phone out of Airplane mode, remove the SIM card and run any GPS aware programme (Maps is good, it's an Apple App, so that removes the 'I wonder if the app is at fault' question). Place the phone in a location where it has a good view of an unobstructed sky, and wait. After 10 or 15 minutes press the "find me" button on the bottom left of the screen. If the "blinking" little blue dot doesn't appear, or if it says that your location can't be determined (there won't be a map), it sounds like the GPS is dead.
BTW, Apple doesn't reply to posts on the forum.
Good luck,

IPhone 3GS GPS problems

I upgraded to a 3GS a month ago. I noticed on a trip with my family that my GPS wasn't working properly. The GPS wouldn't find my position accurately, there was no pulsating blue ring around the blue dot, and the GPS wouldn't track when we were driving. My brother and sister-in-law's GPS was working perfectly on their iPhones. Just mine wasn't tracking.
So I went to the AT&T store and they replaced my iPhone 3GS with another brand new one. The GPS still isn't working properly.
So I went to the Apple Store in SoHo and found that none of the iPhones on display would get an accurate coordinate either. All of them were about a block off with to the west or north and none of them had the pulsating blue ring around the blue dot.
My brother and sis-in-law purchased and use their iPhones in a different city and their GPS works fine. My iPhone (purchased and used in NYC) and the SoHo store (in NYC) iPhones all did not work.
Do NYC used/purchased iPhones only have this issue? It really bothers me that on my 3G the GPS worked fine in the city, but after I upgraded to the 3GS and 3.1.3 the GPS no longer works. Also, the compass app ALWAYS needs to be reset whenever I use the app.
Any other NYC users having this problem?

There's a lot of discussion about receiving the GPS signal indoors. As the USAF Frequency Manager, who licenses the GPS Satellites, I'd like to weigh in on this subject.
The GPS signal is extremely weak, too weak to be received indoors more than 5-10 feet from a window.
A GPS receiver must receive at least 3 GPS satellite signals to get a fix.
For those who believe you're receiving the GPS signal indoors, what you're receiving is the triangulation of the cell phone towers, which is why it's not accurate.
For those in NYC or other highrise building areas, your GPS signal will not be accurate, if even received, because of the reflection of the GPS signals bouncing off of the highrise buildings. As the GPS signals bounce around among the buildings, they're delayed, and therefore not accurate when the GPS receiver finally locks onto them.
Since upgrading to OS 3.1.3, my iPhone 3G GPS has been having fits as well. I'm in Los Angeles, but when it gets cold (sitting in front of the A/C vent in it's holder) it stops working and shows that it's in Boulder, Colorado. It becomes accurate again after letting it warm back up, or turning off 3G. Go figure.

IPhone 3GS GPS not working

So I am gonna try this because I know others haven't got a response they have liked or helped…
I have a 3GS, running iOS on my iPhone 3GS, but still am having issues with the GPS, I am sure others are still having this issue. I found this thread awhile ago, but there wasnt much follow-up on this from Apple, Go to a Genius Bar, plus people in this thread have said that they did that and nothin has worked, or the Mac Genius suggested it might just need the SIM card replaced… I really dont think that would help
http://discussions.apple.com/message.jspa?messageID=11248780
So… Apple can you guys just give some clarity on whats is up with this, I mean I am loyal and keep buying your products, but it is only fair that you share just a lil bit of info like: "an update is coming soon to fix this or its a hardware issue, come on in and it will be resolved."
Let me know if anyone else is still having issues or has a resolution
Thx

What Modem Firmware are you using on the phone?

Want to connect car GPS receiver to iPhone 3GS

Hi,
Getting a little tired with the unreliability of the iPhone 3GS GPS reception in the car so I wondered if I could connect the receiver that is already built into the car. I changed the head unit (the SatNav was pretty basic anyway) for a Pioneer that allows me to control and play music through the car stereo from my iPhone and also lets me make calls via Bluetooth. Is it possible to get a Y splitter that would also allow me to connect the GPS receiver to give me more reliable Satellite Navigation?
Hoping somebody out there can help me.
Steve.

Isn't the iPhone 3GS supposed to have GPS?

I just upgraded to an iPhone 3GS from and original iPhone. One of the features that most excited me was having real GPS, but it seems that this feature is not completely true. I have been doing some tests, outdoors with a clear view of the sky and my new iPhone 3GS is as inaccurate as my original iPhone, which does not have GPS and relies on cellular antennas to find my location.
Is it normal for the iPhone 3GS to be so inaccurate or might it be that my phone has a malfunction?
Thanks,
Cesar

It does indeed have GPS.
It may take several minutes to get a GPS fix. In the meantime it will use the same technology as the original iphone to get a cursory location.

No or bad Bluetooth and GPS with my iPhone 3GS.

Hi all,
I have serious Problems using either GPS and Bluetooth with my iPhone 3GS. First I recognized that my Bluetooth headset was not working as before. For example the connection is dropped quite often and The quality is really bad.
Second I found that the GPS signal is such Bad that no APP like runkeeper or Nike+ can work with it.
Strange is that everything is working well after a reset to factory defaults using iTunes. But both BT and GPS are only working As designed for about 12 to 18 houers. After that timeframe The Device has to Be reseted with iTunes again :-(
Snce everything was working fine a few weeks ago, I guess it has to do somezhing with the latest firmeware.
BTW: The headset IS working fine with other devices and the googlemaps app, included in the iOS is showing a GPS signal (20 to 50 m radius)
Any help is welcome. Please respond to [email protected], thanks!

check to see if there is a firmware update for your router. There are also lots of troubleshooting steps you can take in this article

GPS not working in IOS6 when installed on iPhone 3GS and iPhone 4?

Can somebody confirm that GPS location data (not from cell or wifi) is no longer functioning in IOS6 when installed on iPhone 3GS and iPhone 4?

I have the same issue exept my phone doesn't ring for incoming calls. I've tried every fix, restored the phone and spent over an hour on the phone with Apple Care doing a second restore. The supervisor told me that he hadn't heard of the issue at all and came to the conclusion that I'd somehow broken the silent switch and that I'd have to pay $150 to have it repaired, despite my insistance that it was obviously a software issue since the problem started immediately after I updated to iOS 6. Total BS. I want this issue resolved immediately considering that the phone is virtually useless to me if I have to carry it around and continually check for notifications and incoming texts, phone calls, etc.

After iOS 6.1 update no GPS? iPhone 3gs

GPS fails after ios 6.1 update
Tried three diff apps that worked hours before,
All fail to respond to GPS speed etc?

Hi
I have also the same issue after update to 6.0.1 , 6.1 & 6.1.2 , the problem started from 6.0.1 in 6.0 was ok both GPS & wifi , after 6.1 the wifi has also issues in iphone 3GS!! Apple do something!

HT6146 Doed this update also address the GPS issues on iPhone 3GS?

With IOS6.X (and all other 3GS users) I lost the FULL GPS function I had when I purchased my iPhone 3GS (I assume its behaviour is like an iPod touch now), I was wondering if Apple have included a fix with this update?

I had two users that were unable to get email from Microsoft Exchange 2003 on their iPhone 3GS after upgrading to iOS 4. One other user, however, had no problems after the upgrade. The only difference was that the user with his email functioning had minimal messages in his Inbox.
So for the two other users, I archived email messages to reduce their Inboxes from around 13,000 messages to below 2,500 messages. Once I did this, email started flowing through just fine. I did this to the Sent Items as well, and it worked too. I would give that a try.

Poor GPS reception in IPhone 3GS, am I the only one having this problem ?

Since I have many problems with GPS drop outs and poor signal strength errors when using navigation software for Iphone 3GS firmware 4.0.2.
First I reset my Iphone completely and installed all apps from scratch, but this has not solved my problem.
I now tried several tests to compare with both an Android phone HTC Desire and a very old Symbian phone Nokia E65. Neither the Nokia E65 or HTC Desire have any drop outs in the GPS reception while my Iphone has several dropouts, making navigation horrible.
Am I the only one having this problem ?

Unfortunately, you are not the only one (I personally use TomTom with car kit). This is one of the numerous bugs introduced by iOS4 and this one has been reported by many in this forum. Be careful not to use your iPhone based navigation system in a foreign country, due to high roaming costs ! I had to use it and nearly had an heart attack when reading the invoice.
Apple doesn't care. Unfortunately, I have to care for my budget.

I have an IPhone 3Gs and the IOS 6 locked up my phone 100% whats my next move? wont turn on just the apple and download bar or black screen thats my only options at this point? HELP!

I downloaded the new IOS 6 on my IPhone 3Gs as it prompted me to do so. so that took 45 mins then told me to connect to Itunes in which i did, then it took 39 mins for itunes to "restore" my phone and after the 39 mins it told me Apple unable to restore IPhone and shut me out. Next a screen popped up on my computer screen and said that i could report the problem to Apple if i wanted to. But at this point my phone is completly locked out. So all i get from my phone right now is the Apple on the screen and the download bar under it and or a block screen if i unplug it and the battery dies. which when i did the upgrade my phone was just off a fresh charge! i need help like ASAP i leave out of town on thursday it is monday and i need a phone with GPS and that can make calls! i am pregnate and have a 2 year old i am traving with and we have no house phone so my phone is very important! THANKS!

No. You have no alternative but to plug it into a computer running iTunes and restore it.

IPhone 3gs restores to iOS 4.0 but won't restore to iOS 5 'Unknown Error 1'

I have an iPhone 3gs 32gb that accidentally went through the washing machine a couple of years ago. It was dead and rested peacefully in its box under the bed until a few months ago when I found it and thought - let's try turning it on. Low and behold the little begger worked. It was pretty beat up, so I ordered a new rear case for it and a few fiddly screws later it looked as good as new. It was making and recieving calls ok and recieving email fine - I thought great, I'll plug it into iTunes (10.6.3 on my Windows Vista laptop) and update it. This is when the problems started.
As soon as it tried to install iOS5 it got to the point where it says 'restoring iPhone firmware' and then boom, I get the error message 'Cannot be restored unknown error 1'. I tried installing in DFU mode... same thing happens. So I brought it to work and managed to install iOS4.0 via my work iMac PPC G5 running iTunes 9.2.1 - again, everything worked fine. Calls in and out, internet (both 3g and WiFi) gps, etc., all worked like a dream. So I moved to another iMac that was running the latest iTunes and all the latest updates for Mac OSX. Tried to install iOS5... same issue. 'Cannot be restored unknown error 1'. Arrggghhh!
There doesn't seem to be any hardware issues because the phone works great on iOS4, I just can't figure out what I'm doing wrong when I try to update it. I've also tried downloading the IPSW file and doing CTRL/Option restore and pointing to the file, still with no joy.
Can anyone shed any light on the situation?

Are you sure your replacement is an iPhone 3GS and not a 3? The iPhone 3 can't be updated beyone iOS 4.2.1. If your 3GS was using a newer iOS you won't be able to restore from the backup (the 3GS could be updated to the newes iOS, 5.1). You can check your model number (on the back of the phone) against this list to tell: http://support.apple.com/kb/HT3939.

IPhone 3GS OS 4.0.1 - *****! ruing completely my iPhone User Experience

I just upgraded my iPhone 3GS to the new 4.0.1 OS
why ?
because Apple says in their site "its great".
No one ever told me its going to slow my iPhone performance significantly.
No one ever told me its going to consume my battery so fast, I couldn't leave my office
without taking a charging cable...
No one ever told me I wouldn't be able to downgrade back to the "Factory Default" operating
system.
Hmm sorry - when I upgraded, I clicked on the "Next" button on the "terms and conditions"
and in line 1,847,453 in the terms document it said that this is one way ticket and its my
problem. hmm, sorry I missed it Apple !!!
want some support from Apple ?
PAY FOR IT
want some information, some news from Apple telling "listen, we know, wait a couple of
weeks, we will fix this..." - NOTHING. the only thing you here from Apple is: "We are
perfect! there is nothing wrong with us"
this is crazy.
I was an iPhone addicted and now I am looking to get rid of my iPhone and have nothing to do
with this company.
this is NOT the way to treat your customers, Apple !
All I can tell you:
Never upgrade to 4.0.1 - it will slow your iPhone and consume your battery so fast - you
won't be able to think about anything else except charging all the time.
if you have a whole day out of the office or you are going out of home for the whole day -
forget about your iPhone (with OS 4.0.1). its going to consume its battery completely half
the day through just by talking over the phone.
no apps running, no GPS, no games, no roaming.... just talking... and the battery betray
you.
If anyone know any way to restore my original OS ("Restore" on iTunes do not restore the OS)
- I would love to hear about it. I don't really want to get rid of my iPhone but Apple leave
me no choice.
Bye Bye iPhone
Hello Samsung / Android

And no he is not over reacting. I did the same thing. Trusted Apple that the upgrade was good. After five weeks of syncing not work king, tethering not working and battery draining after two hours at 60% I finally called Apple. Even though my 3Gs is out of warranty, they are giving me a support case at no charge. They got tethering working. They told me that the battery issue is probably due to multitasking. They showed me how to see what tasks are running.
For those or you who do not know; Press the home button twice. All the applications that are running appear. To close them, hold your finger on one of them until they start to 'shake'. You can close the ones you do not want by tapping on the red x on the top left corner of the icon of the application you want to close.
They solved tethering by enabling it in device manager on my laptop.
I can sync calendar and contacts. Notes will not sync. Apple support has now spent over four hours trying to get notes to sync. At one point they had me create a new user on my laptop. On the new user we set installed outlook and i tunes. I created one new note and synced successfully. But back at the original user it still did not work. I uninstalled outlook, renamed the pst files and installed outlook new. I entered one new note in outlook and synced. It did not appear on the phone. Apple had me delete the mobile profile, install new software and try again, oh and disabled avg anti virus and windows fire wall. No success. So now Apple has referred this to their engineers. They say they usually respond in 24-48 hours.
I know this is an issue for many people. So as soon as I have an update I will post it here.

IPhone 3Gs rebooting itself now stuck on boot

Hello,
I've had my iPhone 3Gs since February 2010 making it as of this post 1 year old and 3 months over warrantee. Last week my iPhone started randomly turning off and on again and it was happening a few times each day. It began to reboot itself more frequently, to the point where I couldn't use the phone because it would turn off mid text-message and during phone calls. I grew frustrated and decided to put it into recovery mode to restore the phone, as people on these discussion threads recommended with no luck, it was giving me an error code 29 right when it got to the part to upgrade the firmware (I believe it didn't make it to this point because the phone would turn off). I tried this several times when finally it worked! I restored my iPhone and loaded the backup I had made and charged the phone up and went about my day. As the battery drained it turned on and off more frequently and then went from 30% to 3%. It now will not charge whatsoever on the charger, or through my MacBookPro. It will not boot up at all, but flashes the apple logo then turns black and it keeps doing this over and over. Itunes won't even recognize the iPhone as being connected to my computer.
I don't know what to do. I have never jailbroken this iPhone or tampered with it in any way, and I'm very disappointed that this product is showing such huge issues after only a year of use. Right now my iPhone is completely unusable and I'm hoping that somebody has an answer for me to fix this.

On My iPhone 3GS started with iOS 4.3 and 5.0 did not improve even with the 5.0.1. When started, the device shut down at around 43% battery. Every 2 or 3 weeks the problem got worse ... 53%, 65%, 75%, 86%, 96%, 98% and 100% now it can be turned off.
I realized that if I use the internet through the 3G off at around 98%. If you use the internet through wi-fi, off at around 86%. If you use 3D games off even faster. The first shutdown can be restored by resetting the system (home + power). But after the second or third, it asks to connect to an electrical outlet, the battery even when it was full. If you make a small charge, enough to start the system will turn off at the next mark (percentages cited above). I started using the iPhone always connected to an electrical outlet (house or car).
Recently I made a painful test: I turned off the 3G, wifi and data transmission; stopped to use all the features of the iPhone, except for calls and SMS. The GPS was on, but I did not use any application that needed it. As a result, the battery lasted about 4 days and declined up to 6% (when it fell during a call). I was very glad to review the battery alerts (20% and 10%) after so many months. Then I waited 1 or 2 hours and recharged the phone to 100%. I noticed that charging was much slower than what was occurring before (and remains so since then). But until now I did not notice a difference in the problem.
Other users with the same problem say revert to factory settings did not fix the problem. There are no Apple Stores in my country, only representatives and mobile phone carriers, but the assurance of my iPhone expired in May 2011, in addition, here we have the iPhone 4S world's most expensive (between US$ 1419 and US $ 1,855), the which means buying another iPhone is a last option. Buy another battery would be easier, but I question: if the problem is the battery, why work properly when does not was required 3G, Internet, games or gps?
It would be nice if Apple responded something like "we are aware of the problem and are working on it." At least we could hope to keep until the next update.
