I bought an iPhone off Craigslist not knowing it was jailbroken. The kid I brought it from never said anything about it. I used it for a little over a month then one day it froze & went to the screen saying to connect to iTunes saying it was in recovery mode. So I went to restore it but when it tried to verify it with the Apple store it kept getting an error. I took it to the Apple store & they said it had been jail broken so they couldn't do anything about it. I find it really odd the person didn't say anything about it being jail broken since people usually pay MORE for a phone that is. I see all these programs people download to restore it but I have NO IDEA how they even work. Any suggestions ?
