So I've had At&t for a while. I have a Samsung Impression and we have a family plan of unlimited text and web. I FINALLY bought a Iphone but it's a 2g. Don't mind that. It's jailbroken; which i LOVE. Now, I know I'll have to pay like an extra 15$ a month or something to use internet on the iphone. But my question is...how do i get all this activated and stuff? Just put in my simcard and wait? or what? Also, how do I make sure I keep it Jailbroken while adding apps and such? Also...where can apps be found? Thanks guys.
