Hey guys. I just recently sold my iPhone in an eBay auction and still had a few things I wanted to back up before I sold it. Well I did that and transferred it to my new 3G S but now I tried to restore it to the original factory settings but it says I have to install 3.0. I obviously want to jailbreak/unlock this phone which it already is. What could I do to delete all the data from the phone? Is it still viable through iTunes? I don't mind needing to jailbreak/unlock again since I expected that already. Thanks guys!
