I have sold my unlocked 2G iphone with 2.2.0 software. Now I have no idea what should I do before I hand it over. I'd like to delete all my contacts, SMS, app data etc so that he can use it. Do i simply restore the iPhone using iTunes? Or that will break the unlock/jailbreak? I don't even know how it was unlocked(I paid someone 10$ to do the dirty work for me). I need to ship it off to it's buyer asap. What should I do? I'll be getting the new iPhone once it's available here and would like to c/f all my apps data to that phone. Will simply syncing this iphone with a different computer with a different itunes a/c do it. My guess is that all apps, music, contacts, SMS etc will be deleted in that case which is exactly what I want without risking bricking my phone. Or is there a better, easier way to do what I want? Someone please advice me what should I do. Thanx in advance.
