The UBiQUiO 503G is set to bust out the gate with a fine-looking design aesthetic and sweetly spec'd hardware. This little Windows Mobile 6 device one-ups its predecessor -- the UBiQUiO 501 -- on every front making it a stellar choice for the business set. Featuring quad band GSM, triple band HSDPA, WiFi, Bluetooth, 520 MHz CPU (doubling up on the 501), and a two megapixel camera, the 503G does indeed rock the features we love. We particularily love the one-handed use via the QWERTY keyboard and what you don't see in the pic: a scroll wheel and stylus. That's right, this little bad boy is packin' Windows Mobile 6 Professional, not Standard as the form factor suggests. We have the release date planned around about June 20th 2007 with an expected price tag of $650; no provider information at this point but we will be keeping our eyes peeled.
