So I have an original iPhone (jailbroken and unlocked on 3.1.2), and I plan to sell it really soon. My question is, would a jailbroken iPhone affect the "Erase All Content and Settings" reliability at all, since I want to clear its memory? If it doesn't, should I just go ahead of hit "Erase All Content and Settings" as is, or should I do a restore with iTunes first? Also, I've heard PwnageTool does multi-pass wipes as you can reformat its partitions accordingly; would that be a good means of wiping data? Thanks all!
