Lost APN Setting on Iphone 4 After Upgrade to 4.3.1

I have an officailly unlocked iphone 4 that I bought from the UK. I was using it with STC in Saudi Arabai at 4.0 firmware, I have just recently upgraded to 4.3.1 and I can no longer see the APN setting to edit my MMS or internet settings under setting>general>network. I am not sure what went wrong? I would appreciate any help on this.
Thank you,

Have you checked your apps so that there is no apps overriding the output audio like lock sound etc.
Om my 4S, if I forget quiting spotify and it is running without sound in the background it will disable lock sound etc.
This is just an example and spotify do not disable important sounds like ringing and alarms etc.
But maybe a app is malfunctioning after upgrading to ios 5.1.1
Also you could try restoring the phone like sugested by others in iTunes.

    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?

  • Why missing personal hotspot  in my iphone 4s after upgrade ios 7 ?

    why missing personal hotspot  in my iphone 4s after upgrade ios 7 ?

    I'm having the same issue (iOS 7.0.3 on 5s).
    Had Sprint add Wi-Fi Hot Spot to my account today, went to set it up, and there's nothing in Settings for "Personal Hot Spot." Apparently it should appear underneath "Cellular" but it's just not there.
    Resetting network settings didn't help. And Sprint doesn't know why it's not there either.

  • Why has Siri stopped working on iPhone 4 after upgrading to IOS 5?

    Why has Siri stopped working on iPhone 4 after upgrading to IOS 5? I've tried the disable and reboot but continue to get the network error.

    Apple has not been forthcoming on the explanation. My Siri worked on my iphone4 (not 4s) immediately after upgrading to IOS5, but I take it they have redirected the servers that used to support Siri to only work with Iphone4s.
    It is one thing for apple to only bundle the improved Siri with IPhone 4S, or  for them to remove Siri from the Ap store.
    But it is another thing all together for apple to purchase a company, and then cease the service that many of us paid for.
    Attempts to contact apple at apple store and via email have been unhelpful.

  • 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.

  • Why can't i activate my iphone 3gs after upgrading it to ios 6?

    why can't i activate my iphone 3gs after upgrading it to ios 6?
    It says,
    ''There is no sim card installed in the iphone you are attempting to activate''
    Thanks for your help in advance!

    There are several common causes for this problem:
    Your security software (Antivirus, firewall, router settings) is blocking access to gs.apple.com, Apple's activation servers. Try temporarily disabling your security applications on your computer.
    You have a redirect in your hosts file that defines a different IP address for gs.apple.com. you must delete all references to gs.apple.com from your hosts file (c:\windows\system32\drivers\etc\hosts, or /etc/hosts on a Mac)
    Your phone is jailbroken or otherwise hacked.

  • I cant activate my iphone 3gs after upgrade to 5.1.1

    i cant activate my iphone 3gs after upgrade to 5.1.1

    I am experiencing the same issue and could use some advice:
    Yesterday I plugged my Iphone 3GS into my computer and I selected in Itunes to update to the latest IOS 5.1.1.
    Before I did this the iphone worked correctly, and after I did this it will not let me access the apps at all. I went to the Apple store and the rep told me I needed to have a working AT&T sim installed in it to complete the upgrade. I went to the AT&T store and had them put one of their working sim card in and it would not work.  The AT&T rep said he has seen several people with Iphone 3GS who updated to the latest IOS 5.1.1 whos phones will not recognize the sim card and thus will not let you get to the apps. 
    Does anyone know how to correct this problem?

    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.
