The upcoming Libra Windows Mobile device from HTC is quite a bit smaller than the slide-out QWERTY devices on the market now from HTC. This one looks, for the most part, like a standard dial-pad enabled phone. However, there's a three-row QWERTY keyboard that slides out from the side, compared to the four row QWERTY in the larger devices.
The phone should be available in CDMA form in Q1 2007, and GSM form shortly after. It should support EV-DO Rev. A, so Verizon and Sprint users will get this one first. No other specs have been released yet.
