Siemens has used the CTIA show to announce its new SX1 all-in-one PDA/Phone. The SX1 is an all-around business and entertainment device. It provides PDA, phone, camera, and MP3 capabilities.

It runs Symbian and includes Bluetooth technology. It features a 65,000-color display and an integrated camera on the back of the unit. (This looks very similar to the Sony Ericsson P800 phone.)

It has an integrated FM radio and MP3 player plus a MMC slot. The SX1 sports a quirky number pad design with keys located along the left and right sides of the display.

The phone is expected to be available this fall.
