AT&T's GSM network has been considered one of the iPhone's weak spots, with users complaining about . Apple could be attracted to Verizon not only because of its perceived network reliability and great coverage, but also by reports that its . AT&T also . If Apple jumps from AT&T's network with the iPhone to Verizon's, it would mark the first CDMA-based iPhone and put an end to AT&T's exclusive relationship with Apple, which i.

A Verizon iPhone a Long Shot?

The current generation of iPhone handsets work on GSM technology, used by most carriers here in the U.S. and all over the world. But what makes me take this is that a CDMA (used mainly in the U.S. and Canada) version of the coming in 2010 means that Apple will have to develop a totally new device for Verizon's network. Not likely, as this would mean much higher production costs for the Cupertino company.

Then again, Verizon's customer base of 80 million iPhone-less customers might represent a significant incentive to tweak the iPhone for CDMA support.

Things might change in 2011, though, when Verizon is set to roll out the latest wireless protocol and so are most of the European carriers (a major secondary market for Apple). It will be interesting then to see whether both Verizon and AT&T will get the iPhone, so the two carriers would have to battle it out in tariff prices and network reliability rather than reigning supreme with handset exclusivity.
