The Blackjack, also known as the i607, is a great PDA from AT&T. Full Qwerty keyboard, 3G Support, 1.3 MP Camera, Bluetooth, Windows Mobile software, trackwheel on the side, and even comes complete with 2 batteries and an external battery charger. This is a great all-purpose phone that can do everything from email to music to Cingular Video and just being a good organizer, in a small and light form.
