AT&T gave up its exclusivity contract with Apple for the iPhone, last year. One of the common complaints about the iPhone is that it's tied to AT&T, so it makes sense for Apple to produce a Verizon iPhone.<p>AT&T pays Apple a lot of money for the exclusivity deal, and that deal is part of the reason that Apple has more cash than they know what to do with.<p>AT&T dropped the exclusivity for the iPhone because they picked up a new deal with Apple for the iPad, which they are almost certainly also paying a lot of money for.
