On the heels of rumours of the iPAQ hw6900 come new rumours over at Howard Forums that HP is working on a smartphone. The poster indicates that this device, to be called the rw4500, will run Windows Mobile 5.0. Details on the specs are slim but it looks a lot like the i-mate SP5 and apparently has a 320×240 screen, Wi-Fi and Bluetooth, a 1.3MP camera and miniSD slot. The prototype is also branded T-Mobile on the back.
Check out the forum as there are plenty of good pictures a few posts down in the thread.
