If I wanted to just jailbreak my iPhone with iLiberty will it erase all the settings, pictures and contacts? Or do I have to sync them back onto it. And most importantly, when i've just jailbroken it will I have to do anything to make it recognize a sim card? I mean will it turn on and go straight back to being a iPhone? Sorry if i'm being a bit stupid, i've had a touch for ages! and not a iPhone, lol
