Hi, I am wanting to sell my iPhone 3gs (3.1.2 f/w, 5.11.07 baseband). Of course, I want to restore it so that the new owner has a brand new looking phone and none of my apps are left on it. He also wants it on t mobile, so after restoring I need to unlock it. Right now it is jailbroken (untethered version, blackra1n), and cydia says it has my 3.1, 3.1.2, and 3.1.3 SHSH's on file. So what special way do I need to restore it so that I have a fresh 3.1.2 with the same 5.11.07 unlockable baseband on it? And then after that, I'm assuming I just run blackra1n again and then blacksn0w, correct? Thanks SO much for the help. EDIT: I just realized I could go to iphone settings and choose to erase all data/settings. Would that work to delete my apps, emails, etc. so that I could just do that and then run ultrasn0w and sell it?
