Hey guys, bit of a newb here, I bought an iPhone 3GS on iDay, and now wanna sell it in anticipation of the 4gen, OK, so I knew 3.1.3 with Modem 5.12 can't be unlocked, so I've kept hitting ignore on upgrade from 3.1.2, so I have 3.1.2 with modem 5.11 on there, so I think it can be unlocked no problem. OK, so my question is: How can I restore and erase all my info while keeping 3.1.2 intact? Just hit option-restore? THen how to jb and unlock? Blackrain and then how to unlock? And the last question, isn't there a way to upgrade to 3.1.3 while keeping 5.11 intact? Superbowl Sunday something? Haha. Thanks guys!!!
