So I bought an iPhone 3G from someone the other day, and I went to Settings>Delete all contents or whatever it's called. While it was recovering/deleting stuff, I decided I would just put it into recovery mode and connect it to iTunes to restore it. The problem is, my computer/iTunes won't recognize the phone, and it won't go into DFU mode. I am on a Mac because my computer broke, and I don't know much about Mac's so maybe there is a way to get the phone to be recognized? The phone is on 3.1.2 and the computer has the newest iTunes version. I was trying to jailbreak it with blackra1n as well, and blackra1n won't recognize the phone either. Thanks for any help.
