Sorry, I don't have to believe you. You can believe all you want. How come you have problem now? Mine was officially unlocked and been updating a few times now and I don't seem to have the problem you have.


You can either

Restart

or Reset

or Restore from backup using iTunes

or Restore as new without the backup.


If all else failed, then it only confirmed my belief.

Once again, a lot of thanks to you for attend my help call.

1- I know that is officially unlocked cuz my iPhone was modem baseband 04.11.08 that is unable to unlock it of ANY WAY, NO HACKING WAYS OF UNLOCKING THAT BASEBAND YET, CUZ THE SAM METHOD IS OLD, AND DONT WORK, THE OFFICIAL UNLOCKING IS THE ONLY ACTUAL WAY TO UNLOCK THAT BASEBAND, u can search it on the web.

2- I know that my iPhone is officially unlock cuz they did the official via iTunes unlocking proccess, AT&T told Apple to whitelist the phone, u can search it on net, when u look your iPhone from (iTools, SAM, and other softwares) and it says Factory Unlocked IS A LIE, the official unlocking says WildcardActivated.


I want to update my status, I was with deactivated 3G in my iphone, yesterday I activate it and dont present problems since yesterday, so, lets see, super good working 100% real good signal, cuz im checking it through the Field Test. Maybe that was the total problem.
