The FCC has given its approval to not one but three Kaiser models. All three will sport Windows Mobile 6 Professional, 128MB RAM and 256MB ROM, quad-band GSM/GPRS/EDGE and tri-band UMTS/HSDPA, a 2.8-inch QVGA screen that tilts when the keyboard is out, a slide-out QWERTY keyboard, 802.11 b/g Wi-Fi, Bluetooth 2.0, integrated GPS, and a microSD slot. But the Kaiser 100 will not have any camera, the Kaiser 110 will have a 3MP camera on the back and the Kaiser 120 will sport the 3MP camera as well as a front-facing VGA camera for video conferencing.
Based on what we know so far, the HTC P4550 is likely the 120 variant. The other two may be rebranded and headed to carriers such as AT&T (as the Cingular 8925 perhaps?).
