scooped well ahead of today's announcement, but it's always good to see official details get laid out nonetheless. Following hot on the heels of its elder Windows Mobile sibling, the 750v, the Treo 680 comes into the light today for GSM networks -- a good sign for carriers worldwide after a year of CDMA equipment out of the company. Cast as an entry-level model (read: no WiFi support), the 680 brings it strong with a redesigned phone UI and software bundle, quad-band GSM (what, no quint-band HSDPA?), 64MB of RAM, and a VGA cam, all sitting atop Palm OS in the buyer's choice of Graphite, Copper, Arctic, or Crimson colors. No pricing or launch carriers were announced today, but given the branding we've seen on some of the shots thus far, we've got our guesses.
