I'm thinking about jailbreaking my 8GB Touch. My friend just jb'ed his iPhone and he says its awesome but he tried to JB his brothers touch using ZiPhine(I think) but he messed up b/c his touch wasn't updated. Has anyone here unlocked their Touch using ZiPhone? Does it work 100% of the time? Any chance of bricking? Thanks so much in advance. These are all pretty east questions but I'm a nooblet in JB'ing. Edit: if I jailbreak, is there anyway to un-jailbreak? Like it if I don't like it or if there's a nice update for the touch can I "re-lock" it.
