Verizon iPhone? Not this year.

AT&T has reportedly negotiated an extra six months as the exclusive carrier of the Apple iPhone. How long will we have to wait to see a Verizon iPhone?

Back in March, a very tantalizing rumor began weaving its way across the Web: The Apple iPhone, long tethered exclusively to AT&T, would soon become available on the Verizon network. A Verizon iPhone? Exciting!

Well, hey – not so fast. According to one Wall Street analyst, Apple has now extended its exclusive partnership with AT&T for at least six more months, meaning that Verizon users probably won't get their mitts on an iPhone before 2010 is out.

"AT&T had to do something dramatic to get the iPad," Brian Marshall, an analyst at BroadPoint AmTech, told Computerworld this week.

Marshall said that AT&T agreed to discount the wireless data plans on the new Apple iPad; in exchange, Apple gave AT&T "a six-month extension on the iPhone exclusive." Neither Apple nor AT&T have responded to requests for comment.

Marshall's analysis comes weeks after a major dust-up over a lost iPhone 4G – and weeks before Apple is expected to make some sort of announcement about new edition of the top-selling iPhone. Several tech insiders have predicted that the iPhone 4G will launch on Verizon and AT&T. But if Marshall is correct, iPhone users will be stuck with AT&T, a network which has struggled to keep pace with heavy iPhone call volume.

AT&T has ample reason to fight off a Verizon iPhone.

In a recent survey by ChangeWave, approximately half of Verizon's current customers said they would switch to a Verizon iPhone, if one became available. A Verizon iPhone would mean that Verizon users would no longer have to switch to AT&T to get the phone. Conversely, it would mean that disgruntled AT&T customers could switch to Verizon to get better service.
