Verizon even set aside a limited quantity of iPhones for existing customers, and orders will be shipped to arrive on or before Feb. 10, an interesting PR move since bringing the iPhone to the carrier is expected to attract customers sick of AT&T dropping their calls. Classy, Verizon.

The iPhone 4 will be available for non-Verizon customers on Feb. 10, priced at $199.99 for the 16 GB iPhone 4 or $299.99 for the 32 GB iPhone 4 with a new two-year customer agreement. A data plan is $29.99 a month.

Early reviews of the Verizon iPhone say the call quality is crisp, but the data conntection is much slower and the phone can't handle as much data and voice action at the same time as its AT&T counterpart.

"While it isn't all rainbows and flowers (the data speed issues or the voice / data considerations could be a dealbreaker for some), it does kind of feel like Apple and Verizon did the impossible: they made the best smartphone in America just a little bit better," Engadget's Joshua Topolsky, who lives in Brooklyn, wrote after testing the device. David Pogue at The New York Times ran around New York and other cities with the Verizon and AT&T iPhones and was impressed.

There is still fear that the AT&T diaspora could affect call quality for current Verizon customers. We won't know if that's true for another two weeks.
