So i've heard alot of people saying that there afraid of reselling there iphone/ipod touch because there are ways to retrive the iformation even after you restore it. people have gotten the previous users data off an iPhone that apple had refurbished. even kevin rose from digg nation won't give away his iPhone because of this. and i thought to my self couldnt you just delete all the ifo off when you ssh into it? so i looked it up and i found this hopefully this will help some people. I haven't tested it and I'm not going to because I have no intentions any time soon to resell my iPod touch!
