I have a phone-less iPhone. It was "fake" activated using Independence back when 1.0.2 was the firmware. I did not unlock it as I don't use it as a phone. Since then, I installed AppTap and a bunch of apps. I have 4 questions: 1) Is there a downside to upgrading to 1.1.1? 2) Is the phone in danger of being bricked in someway or have all those problems been solved? 3) Is it possible to restore my phone back to its virgin state at 1.0.2 if I move to a hacked version of 1.1.1? 4) If I upgrade to 1.1.1, if I ever want to legitimately activate my phone and use it on AT&T, can I still do so? Thanks!
