Cingular formally launches Siemens SX66 Pocket PC Phone

Not sure why they waited until today to make the "official announcement," since it's been dribbling out in retail channels for the past month or so, but Cingular decided to pick today to formally launch the Siemens SX66 Pocket PC Phone (yes, it's basically the Blue Angel/XDA III).
By now you probably know the drill—it has a slide-out QWERTY keyboard, 3.5-inch LCD screen, 400MHz Intel Xscale processor, quad band GSM/GRPS, an SDIO expansion card slot, built-in Bluetooth and 802.11b WiFi. Retail price: $499.99 after rebate.
