If you're looking for a slim candybar-style handset with decent data capabilities, you should definitely take a gander at T-Mobile's Samsung t509
, which just got priced at merely fifty bucks after rebates, discounts, and such. You'll probably recall that the ~0.4-inch thick t509 is a tri-band model that also features Bluetooth and a camera with 4x zoom (whose resolution is still unspecified, which almost certainly means VGA). This model gets its Internet on through T-Mobile's EDGE network, and also sports such amenities as a speakerphone, pre-loaded IM clients, and some kind of ringtones that must be good because their names are trademarked.
