Hewlett-Packard unveiled a new iPAQ model aimed at GSM-equipped phones, but that also features Wi-Fi and Skype calling capability that will enable users to trim calling costs leveled by GSM service providers. The announcement came Monday at the 3GSM Congress in Barcelona.

The device, the HP iPAQ hw6900 Mobile Messenger, is the first product move by HP as it prepares to spin off its hand-held business from its notebook unit.

The hw6900 features radio bands GSM/GPRS/EDGE/Wi-Fi/GPS/ and Bluetooth all enclosed in a 4.65x2.8x0.71-inch housing that weighs just 6.33 oz.

The Wi-Fi 802.11b capability means that the new iPAQ can be utilized for free calling with Skype Mobile software. The hw6900 also includes GPS capability and customized navigation features for different markets. The device will be available first in Asia, Pacific, Europe, Africa and Middle East markets this spring and in North America this summer.

The new iPAQ also includes a 1.3-megapixel Photosmart digital camera.
