Palm's new Tungsten C handheld will be released in the US around the end of April as the first Palm-branded handheld to use one of Intel's XScale processors, according to a source familiar with the company's plans.

The Tungsten C was entered into the ordering system at office supply company Staples in America in February for $499.99 (£320), but Staples employees were unable to confirm any details at the time. The Tungsten C will feature 802.11b wireless technology, in contrast to the Tungsten W handheld, which uses a GSM/GPRS (global system for mobile communications/general packet radio service) module for wireless data communications.

The Tungsten C marks a design win for Intel over Texas Instruments (TI) and Motorola. Motorola's Dragonball chip powers the Tungsten W, and the Tungsten T uses an Omap chip from TI.

Intel's XScale processors for handhelds have mostly been found in personal digital assistants with the Pocket PC operating system, but a few Palm OS devices exist, such as Sony's Clie.

A Palm representative could not be reached for comment. Intel declined to comment. No details of a UK launch are available.
