When you made the upgrade from 2.2 to 3.0, it relocked your phone to AT&T. You'll have to unlock your iPhone again to get it to work.

I have an iphone 3g with firmware 4.2.1 and want to upgrade as i'm not getting a lot of apps as they need a higher firmware


Go to itunes. There, wait for itunes to recognize your iphone. It will then ask you if you want to upgrade. Click yes. If it doesn't ask you if you want to upgrade, try to find the manual button that says upgrade. Don't try to upgrade without using itunes

Call up tmobile, do not tell them you have a rooted phone or that it was modified in anyway, otherwise they will blame it. They will be able to help you get it working by modifying / adding some settings in your phone.

Unlocked verizon blackberry world phone wont work with t-mobile


i believe i had had the same issue.

i unlocked an at&t phone and put in the sim card and it wouldnt work. i called tmobile and the representative told me that they have to register the sim card to their network or something.

so just call tmobile and tell them you got a new phone and want to register it so the sim will work in the unlocked phone.
