ok, so i am picking up a 2g iphone tonight. i previously had one last summer and used ziphone to jb it. never had any issues and it worked like a charm on tmobile. ended up selling it before winter and now i am picking another one up. after reading some info/rumors/etc... some have said that the ziphone software was really someone elses that he skinned to be his "own". my question is, what JB/unlock options do i have now, and which one is considered the "best" and most stable?
