Thread: 1.1.1 & Any AT&T SIM Card?
10-07-2007, 04:33 AM #11.1.1 & Any AT&T SIM Card?
I understand that downgrading an iPhone from 1.1.1 to 1.0.2 will enable the process of jailbreaking. What if I downgraded a brand new iPhone with 1.1.1 out of the box(never unlocked) to 1.0.2 and went through this process of using ANY AT&T SIM:

Correct me if I'm wrong, but this is not unlocking and it just 'tricks' the iPhone into thinking that the new AT&T SIM was the original preinstalled AT&T SIM card. It seems like I would be able to use my calling & sms features again but I'm just concerned it might conflict with the updated modem. Any opinions? Thanks!
