IPhone 4 (GSM Model) Touchscreen Presses by Itself?

I had gotten my iPhone 4 on July 15th, 2011. One day, the touchscreen became unresponsive and started to press random parts all on its own, therefore calling and sending text messages to my contacts. The iPhone became uncontrollable after that.
I had tried restoring to iOS 4.3.3 three times, however the restore failed with an error message from iTunes all three times. Then the iPhone got stuck on a recovery loop. (The screen with the USB cable and the iTunes logo.)
I had sent it in to the Apple Store for servicing.
Unfortunately, it happened again twice for the past 2 days.
However, this time I was able to restore to iOS 4.3.5.
My friend had told me that her boss in Taiwan also had this issue with his iPhone 4, but he got a replacement for his iPhone.
Can anybody help?

yes my iphone4 is also listed as iphone3.1

How to pick the iPhone 5 model (CDMA, GSM, ETC...) when buying it unlocked online?

Hello,
I want to buy an unlocked iPhone 5 to be used with Virgin Mobile Canada. VMC uses CDMA network, and as some of you may know, iPhone 5 has 3 different models:
GSM model A1428*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 4 and 17)
CDMA model A1429*: CDMA EV-DO Rev. A and Rev. B (800, 1900, 2100 MHz); UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5, 13, 25)
GSM model A1429*: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5)
So the first one, Model A1428 would not work with VMC i guess, right?
That leaves me with the other 2 models. The second one works with CDMA and GSM and LTE, so If i get this model, it should work on CDMA networks (Virgin Mobile) and GSM too (eg. Rogers), right? And LTE would work on both networks, right? (also whats the difference between the LTE bands? like what does it mean?)
So Virgin Mobile itself supplies customers with the A1429 model right (and so does Bell)? While Rogers supplied the A1428 one, right?
Finally, how do i PICK which model to buy? I mean when i go on apple.ca and "Buy iPhone", it doesnt ask to pick a model, so how do i specify which one to buy?
Thank you all (btw, please dont pay attention to my weird username as I once used this forum before and entered the topic in the username field, and it doesnt really give an option to change it in my profile, haha)
Thanks again!

But i actually asked them, and they said that its fine to bring my own iPhone. I'm looking into a prepaid plan (that come with some data), so it shouldnt make a difference, because theyre gonna activate the sim card and ill go from there with top ups (so basically they wont even know what phone i'm using).
So anyway i asked them, and they said its ok. but i then thought of the whole cdma thing

Do I get full conference call management options on iPhone 6 model A1549 if using it with GSM carriers?

I have iPhone 6 model A1549, bought from and currently using with Verizon. You all must be aware that we can use the same phone for GSM carriers like at&t as well. Now we all know that some of the features related to conference calling are not available on CDMA carriers, like we cant have more than 2 callers, and we can't manage conference calls by making the conversation with one party private for some time and again switching back to conference mode, disconnecting a particular party instead of having to end the entire call etc. reference link- iPhone: Understanding phone features - Apple Support These features are available on GSM models and carriers, I just wanted to ask if I use a GSM SIM from a GSM carrier on this model, do I get these additional conference call management options or I am restricted to Verizon like experience while being on at&t (and while using the at&t SIM in this model)

Yes, I am dealing with this right now on at&t with a 6 plus. I've been down the same road as you. I got it to work with a windows phone yesterday but not my 6 plus when I switched back to the iPhone. My wifes 6 works fine. I believe it is an at&t issue and not an 8.3 issue. After dealing through several levels of support at at&t, they are telling me it has to do with their transition to hd voice. Some people are having this issue because they are updating their system and some peoples phone profile, on phones that have hd voice capabilities, are not getting added to their line and call forwarding will not work without it. I have a trouble ticket open to their engineering dept and they promise it will work for me on or before the 24th of april. Engineering has to build my phones profile so call forwarding will work with my iPhone.
This is frustrating because like you, I need to forward my calls because I have no signal in my office and need to forward to another phone so I can get my calls. If at&t would quit dragging their feet and enable wifi calling, this wouldn't be an issue for me. I would suggest you put more pressure on at&t and escalate this until it gets resolved. Or put your sim in a phone that does not have hd voice capability and see if it works then.
Good luck. I'm keeping my fingers crossed this will be fixed for me on or before the 24th. We'll see.
EDIT: I see you did put it in another phone and it worked. That backs up that the issue is at&t and their hd voice upgrades. They had no explanation as to why some work and some don't, but have them make sure a profile for your phone is on the line. If not, they'll need to build one for the phone so that it''l work. At least that's the story for now. Like I said, I'll know more in a day or two.

I would like to know if iphone 5 GSM model A1429 unlocked is available in stores in the US in order to buy and use in Europe

Thanks

Not officially for sale in the US, at the present time, although Apple's flagship store on 5th Ave, in New York City, gets supplies from time-to-time. However, no GSM US model iPhone 5 will support LTE anywhere other than North America. It will not support LTE in Europe. If you want LTE support in Europe, you need to purchase your phone in Europe.

You need a Sim inside the iPhone to activate it. If the iPhone is locked to a carrier, you need a Sim from that carrier. The person who sold you the iPhone should be able to give you that information, but if it is not available, you need to get it from Apple Care. Call them.

IPhone 6 Model A1586 (GSM)

How can I buy an unlocked iPhone 6 Model A1586 (GSM), online on the apple.com - delivery to be in USA?

Unlocked phones are not yet being sold in the US.
If you order a phone from apple.com, you must have a valid US credit card, billing address and mailing address. Warranty would also only be honored in the US and you may not get 4G/LTE service in any other country.

That's the only model iPhone 5, sold by Apple as officially unlocked, in Europe. Thus, if you order an officially unlocked iPhone 5, that's what you'll get.

What are the different iPhone 5 model numbers?

What do the different model numbers mean for the iPhone 5? I see some that start with an "A" and some that start with "MD"? Which model is for what?

Is the iPhone 5 model A1428 usable in India?

Hi,
My cousin in the us has gifted me a iPhone 5 model A1428. I'll be predominantly using it in India. It's supposed to be a company unlocked phone according to the product discription on Amazon. My question is would it be usable in India on a non AT&T carrier provided the gsm band width is 900 -1800 MHz? The phone came with a empty sim tray. The package also didn't have any literature to suggest that it's usable only on AT&T network. The phone is still with my cousin in the US but em need to decide whether he gets it to India in the later weeks of December. If it's not going to be usable here, it's of no point him getting it here.
cheers,
Gautam

Hmmm. I just ran GeekBench here in Sydney and it has identified my A1429 iPhone 5 as a CDMA version. Whatever, it is running fine on LTE on the Telstra network here.
Is this just a glitch in GeekBench or is Apple really using the Verizon A1429 version interchangeably with the GSM-only A1429 as the world-phone?

HT1937 is cdmasim work in iphone 5 model-no-A1429 please give me the answer ?

is cdmasim work in iphone 5 model- no-A1429 please give me the answer ? i am in india

No. A CDMA iPhone can only be used on the CDMA carrier it was originally sold for. IF the GSM side is unlocked, as in the case of the Verizon iPhone 5, it can be used on any compatible GSM carrier. It can not be used on a different CDMA carrier.

IPhone 5 model A1429, part MD105LL/A/

I am looking at buying a used iPhone 5 model A1429, part MD105LL/A. Trying to find out if this is an original Apple Store unlocked phone that is GSM version?

From the part number, that appears to be a CDMA Cricket model of iPhone. Those are not unlocked and to the best of my knowledge Cricket will not unlock it. I'd therefore suggest avoiding that iPhone. In fact I'd suggest avoiding buying any used iPhone if you're looking for one that's unlocked unless you can buy from someone you know or the seller can provide you proof that it was either sold unlocked originally or was unlocked by the carrier. Most "unlocked" iPhones sold used are actually hacked, not unlocked officially.
Regards.

Craig,
Your analogy is excellent! Perfectly captures the opinion I have heard from many. The reason that I have encouraged you to update is because really I, personally, have never experienced an issue with an update, and neither has my signifiant other. Call us lucky! I will not lie to you and say that that means that all updates are going to flawless -- far from it. Many people, as you described, find themselves in the exact situation described by your analogy, and they take to the internet to describe and outline these problems. It is unfortunate that iOS 8 has been such a buggy release for so many, and disheartening that Apple has not yet found a solution for some of these major bugs.
I do ask you to remember though that most of what you find when looking for opinions on iOS 8 will be people having problems with their device -- those whose update went through perfectly have no reason to question it, and thus it can make it seem like everyone writing on iOS 8 is having a problem. There is most definitely a large amount of people with problems after the update, but most likely an equally large amount of people who did not have problems and simply didn't post about it.
My significant other is not a heavy user. She uses her phone an average amount, but she most definitely does not rely on it as much as you have outlined above. I do not want to deceive you into thinking that just because she had no problems that means that you will not encounter any either. To answer your question, she updated about a week after each release of iOS 8 (iOS 8.1, iOS 8.1.2, etc.)
I also do not want you to think that I am a completely neutral party either. I am a fan of Apple, I will admit to that, but trust that I try to speak from as unbiased a position as I possibly can.
As far as your concerns with Apple go, I hear you. Many people would agree with you. Apple markets itself with the concept of flawlessly functioning devices, and that means that for some, when issues do occur, it is even more than just a bug because they bought the device on the promise of it flawlessly functioning. Yes, the functioning factor is part of the reason behind the higher prices of Apple products, but remember you also get a one year hardware warranty and over the phone assistance, access to the Apple Store and Genius Bar (both of which have excellent customer service, a fact that is widely agreed upon), as well as features such as iCloud storage. Widespread bugs like the ones that have occurred with iOS 8 are uncharacteristic of Apple, but in the end they will make mistakes, it is how they fix them that characterizes the company.
From everything that you have stated, here is my solution for you: If your phone works right now, it works. It will continue to work if you do not update, that is guaranteed. What is not guaranteed is that if you update, the phone will function even better. Both you and I are aware that iOS 8 has caused just as many issues as it has resolved -- updating here is a gamble, if you rely on your phone as much as I am thinking you do, it is probably better to take the safer route that guarantees the phone will work. Keep in mind, iOS 8.2 is right around the corner. More bug fixes may be introduced, and that may be a better time to update.
You bring up some excellent points. In the end, this decision is all up to you. I'm just a guy on the internet with some strong opinions!
Nick.
