Hi Guys, I'm new to the world of iPhone and At&T. My contract with Verizon is up in August and I am counting down the days until my new iPhone. My question is - should I head to the nearest Apple store or the nearest AT&T store? Seems like if I were just interested in the device I would prefer to get it from the Apple store - but the AT&T store might better be suited to start my new service and cancel my old? Should I just head to whichever is closer?
