I've got an 2G iphone with FW 2.1, which I have installed using Pwnage under Mac OS X 10.5. Right now, I've got OS X 10.5.6 and iTunes 8.0.2. NOw, someone told me that in this case I can just click the "upgrade" button in iTunes to install FW 2.2 on my iPhone, and it would still be unlocked! Can someone please confirm this info? Best regards, G.
