I think this is probably discussed at length somewhere on this forum, but I can't seem to find the "intro level" discussion! I am just buying my first iPhone, though I have had my wifi only iPad 1 since day 1. My question: how do I set up the phone and iPad so that I can connect to the internet from my iPad using the iPhone as a personal hotspot? Does it depend on the carrier, in my case AT&T? If you can answer my question or point me to the appropriate threads, I would appreciate it greatly‘ Thans.
