Hi Sorry couldn,t search as you can imagine searching jb brings up millions! I want to know what a jb means? I understand what a propriatory system is and realize apple imposes certain locks, but what sort of things does a jb open up. Sorry for the nievety, I,m really asking for literal answers - I know you can then use installer but how does that help? I'll be honest, I just don't really know how a jb will help and I love my ipt2g as it is and everyone seems so excited and I do to - I don't really know why!!!
