Where Should You Buy an iPhone, Apple or AT&T? (Answered)

When the iPhone 3G hits July 11th, it will be available at both AT&T and Apple stores. So beyond a little extra pretentiousness at the Apple stores, is there anything different between them? What if you need to start a new plan? What if you need to transfer a number? Can Apple handle the complicated stuff? » 7/02/08 3:10pm 7/02/08 3:10pm
