Hey guys, I have unlocked my 1.0.2 and I'm using it on the T-mobile network in the US. Is it possible to upgrade to 1.1.1 and unlock it without causing permanent damage? If so, what is the recommended method? (e.g. relock? virginize?).
I'm on Mac platform BTW.
[EDIT- I should probably add that I used the free Dev Team unlock method for 1.0.2 firmware.]
