WinPwn - Quick question about Official AT&T Carrier
So I jailbreaked several iPhone 3Gs with winpwn and all of them did not accept an Official AT&T sim?? (it just shows no signal). What am I doing wrong?
I thought after the jailbreak it will accept any AT&T sim or Cingular sim or am I misunderstanding?
Also I think I checked the "activate" option could that be the problem? All I basically need is for the iPhone 3Gs to be able to work with "any" AT&T sim card even the ones that are not on a iPhone plan. Some input would be greatly appreciated.
