How I fixed my crashing iPhone 3Gs after upgrading to iOS 4x

My experience...iPhone 3Gs, working fine until I upgraded to the iOS 4. I have two wi-fi zones that I use, 1 at home, 1 at work. Home is DHCP pushing out an IP address, at work manually IP address. All this changed after upgrade and crashed durning calls at home and work. Then it got worse and started crashing/rebooting once a day. I rang Apple support and, as advised, in iTunes restored my iPhone and set it up as a New Phone. Ok for a day but it got worse than ever, so I tried the following: worked for 3 days with 3Gs only, wi-fi off...no crashing, worked for three days wi-fi only, 3Gs off...no crashing. Then put both back on again, back to square one, crashing. I tried one more thing. I entered Settings, General, Reset and Reset all Settings. That was 10 days ago, no more crashing at all. Now I had to setup all my seting again, but it was worth it...I love my iPhone again! Try it...

Did you check your security software settings? eliminating conflicts from third-party security software.

    how can i activate my iphone 3gs after upgrading to ios6? it could not activate....

    If your phone was previously hacked to unlock it, when you updated the hack was removed and it's re-locked to the original carrier.  The phone will now activate and operate only with that original carrier.

  • Reception / Battery problems with iPhone 3GS after upgrading to iOS 4.2.1

    There are major reception and battery problems with iPhone 3GS after upgrading to iOS 4.2.1.
    I can not believe that Apple did not test this for major bugs like this one is.
    I am a business user and can not effort to have bad reception. Apple wants to gain in the business clients... I never had this with my former BlackBerrys!
    I need a reliable phone not a play thing like this is right now, it just needs it to work propely. And if a major bug like this comes along, fix it immediately. After the iPhone4 story, now this...incredible! Going back to my reliable BlackBerry! It just ain't reliable and takes forever to fix a problem.

    I have the same issue after iOS 4.2.1 update. I am using iPhone 3GS officially unlocked by Apple. I tried using different SIM cards and both carriers show same problem when using phone in 3G mode. Phone falls back to EDGE mode showing 'E' from '3G' at start. I have reset the phone and rebooted several times and moved to different cell areas in the city just to verify the problem.
    I had no such issues earlier. I also have Nokia E71 which shows full signal and has no such issues.
    I have posted the bug on apple iphone feedback page. I hope they Apple will fix the problem and test the release properly on all models before releasing to public.

    how do i activate my iphone 4 after upgrading to ioS 5.1

    I'm not sure I understand what you're asking, but I'll try to answer!    You can either connect to iTunes and set up and activate there, or you can also use the setup assistant to set up your iPhone.  As far as carrier activation, you'll have to follow the protocol that your carrier uses.  Either switch SIM card, or call the number they use to allow device activation.  Is that what you were wanting to know?

  • Reception problems with iPhone 3GS after upgrading to iOS 4.2.1

    AFter upgrading to 4.2.1, my 3GS iPhone is experiencing bad signal, bad quality and frequent disconnections.
    This was repeated even after my provider replaced my device to a different 3GS device, running 4.2.1.
    inserting my SIM card to a NOKIA phone, showed strong signal and good reception.
    Did anyone experience reception problems on 3GS running 4.2.1??
    Thanks,

  • Problems on iphone 3GS after upgrading to IOS 6.1.2., Problems on iphone 3GS after upgrading to IOS 6.1.2.

    Hello all,
    Some urgent help needed on the 3 problems listed on priority basis, as follows.
    P1 -> I upgraded to IOS6.1.2 on my iPhone 3GS last week and all worked fine for 2 days. Then, last Thursday (21st February) evening, the mail app started crashing and is currntly unusable. All efforts to Restart/Reset, have failed.
    P2 -> With the SMS app, there is no sound/vibrate available, whenever a message comes in. Pretty annoying!
    P3 -> There is extremely heavy battery drain, resulting in the phone having to be charged atleast 4-5 times a day.
    On the upside, after the upgrade, the phone works really fast.
    Could any of the gurus over her, offer any help or insights please?
    Thanks & Regards,
    sworld

    Backup, Restore in iTunes afresh, Setup as new, Sync personal data back with iTunes tab helps many.
    Cheers

  • The new Reply with Message or Reminde me Later options are not showing on iPhone 3GS after upgrade to ios 6

    I just upgraded 2 iPhone 3GS to ios 6 and on neither one is there an option to "Reply With Message" or "Remind Me Later" when there is an incoming call. There is no little phone icon (like the camera one on the lock screen) that you can drag up to expose the new options. Is there something more that needs to be done to enable these features? I tried changing the 3 canned messages from the settings but with the same result. From what I read this is suppose to be available on iPhone 3GS

    Swiping up does nothing, the options do not appear. I tried swiping up all over the screen when a call comes in and nothing. The incoming call screen looks identical to how it appeared in ios 5. My understanding was that with ios 6 there is supposed to be a little phone icon in the bottom right hand corner (similar to the camera icon on the lock screen) appear on the incoming call screen and you swip up on this icon to reveal the options. This icon is not shown on the incoming call screen on either phone.

  • Itunes won't recognize iphone 3gs after upgrade to IOS 5

    Backup for Iphone on itunes was made on DELL INSPIRON MINI 10 laptop running XP Professional, Thursday evening 10-13-2011.
    Upgraded Itunes to new system (ios 5) Friday evening 10-14-2011.
    Connected Iphone to laptop Saturday afternoon to sync and upgrade phone to ios 5. after 2 hours phone was wiped clear, and itunes dropped recognition icon from list. several attempts were made to re-sync. all failed, itunes would not recognize. ended up restarting phone and installing upgrade on another computer. Laptop still failed to recognize.
    attempted upgrade to Ipod and it locked up on "Disconnect before removing'. opened Itunes dropdown and selected 'Diagose devise' and was able to restore ipod and sync with itunes. afraid to attempt 'diagnose' with iphone, now that it is working.
    back-up for iphone still appears on itunes,,,, just can't back it up...XP is unable to 'ICloud' and my DELL Window Vista Home Premium won't install updates so ICloud won't load....

    Help please - my computer does not recognize iPhone after upgrading to IOS4 and iTunes 9.2 ---- I have WIndows 7 --- have tried EVERYTHING and still it does not work. I want to do my albums via the computer, not iTunes since it adds the Photo Library folder, which is a duplicate of all my picture folders.
    Does anyone have a real solution please? I have uninstalled, installed, deleted drivers, installed drivers - the computer says the drivers are working, but obviously not.
    When is Apple going to post the solution so that people will know what to do - seems everyone has an idea, but none are working for me and the extra photo folder frankly drivers me crazy ---- something about iPod cache ----- do not want duplicate pictures.
    And, will albums be able to be edited - can these pics not be sent to Facebook.
    I know, several topics ----- what a mess Apple has created with IOS4 and iTunes 9.2. Ready to send the phone back!

  • Album Artwork missing from Iphone 3GS after upgrading to IOS 5

    I cannot open/click my iCloud (iphone 4s) after upgrading to ios 7.0.6... How can I fix it?

    Hey AU Nicasio,
    Thanks for the question. If the iCloud tab (and other tabs) are greyed out, and you are unable to tap on them, it sounds like Restrictions have been enabled on your device. Specifically, the Restriction titled “Allow Changes: Accounts”.
    For more information, see this resource:
