Sony Ericsson W810
Bit the bullet
After waiting for months for Cingular to release it, all the while dealing with a glitchy, worn, and tired T637, I finally bit the bullet and picked one up from eBay for $330 shipped. Needless to say, the phone is fantastic. While not as flashy in appearance as some of the other phones on the market, it is sturdy, small, and feature-filled -- really almost all you would want in a mobile. I highly recommend it.
