The phone is slated to arrive in the fourth quarter of this year and will feature Windows Mobile 6. It will have EV-DO Rev. A support, a 320 x 320 display, 256MB flash memory, 128MB RAM memory, a 1.3 megapixel camera, WiFi, Bluetooth, an expansion slot and GPS!
The big ones are of course Windows Mobile 6, the increased speed of EV-DO Rev. A, Wi-Fi, and that larger screen resolution. The 320x320 resolution is square, yes, but nothing that Treo fans haven't gotten used to already. Plus, it's the first phone announced to support the 320x320 resolution that WM6 offers.
