I activated my att go phone prepaid sim and all that it works but when I put the sim in my iPhone 3GS it says searching… And then no service. I have tried everything
Turning off and on airplane mode
Disable 3G
Restore iphone
Etc.
I have put my brothers AT&T SIM card in and it works perfect. If I downgrade the baseband will it work?
Base band 5.16.08
HELP ME!!!
