I have a 16GB 3G iphone that is jailbroken 2.2.1 but not unlocked. I left it at my neighbours and his stupid drunk ass must have kept entering the wrong password trying to get into my phone. Well any way, how can I get it working again? Will it need to be restored and won't that upgrade it? I would be very grateful as this is my only phone line and I don't wanna restore if it'll stop me from jailbreaking.
