The Palm OS Treo from Sprint gets a makeover. Sporting the Treo 680 and Treo 750's new design, the smaller, curvier Treo 755p is a welcome update to the Treo 700p. The improvements are more than skin deep with stronger Bluetooth, improved voice quality and better pictures from the 1.3 megapixel camera. The Treo 755p runs Palm OS 5 (Garnet) and is a CDMA phone with EVDO for Sprint. It has a 320 x 320 pixel display, Bluetooth 1.2. MiniSD card slot and a higher capacity battery than the Treo 680 and 750.
