I have been reading a lot of posts trying to find the best method of jail breaking an out-of-the-box 1.1.3 iPhone, and I have seen some issues, and have not found if they are resolved. I have a brand new iPhone with 1.1.3 installed. I have a iBook G4 (PowerPC) Mac. I have the AT&T iPhone service. And I would like to know if I can use the guide on this board to jail break, or if I am out of luck because I have no access to an Intel Mac? My goal is to have a fully working iPhone with my AT&T service, and the ability to run 'unofficial' 3rd party apps. Thanks for your help, sorry in advance if this question has been answered many times.
