Unlike previous PTT phones, the Motorola Pax will use Sprint's new CDMA 1X technology which is a step up from the old system. Other important things like pricing and launch date are not known. And one piece of info that we are anxious to see is the size and resolution of the display. The 3.1 inch screen with resolution of 320 x 480 on the XPRT is a sore point with many users and if the Motorola Pax is going to offer a dual-core processor, why waste that speed and power on a poor display? We would expect to see the rest of the specs worthy of a high-end Android phone.
