HP's first Windows Mobile 6 device--the iPAQ 510 Voice Messenger--is now available in some stores, though without any operator subsidies. It retails for $320.

So if you live in the US, check out your local HP or generic gadget store. But only if you want a quadband GSM smartphone running on Windows Mobile 6 standard (previously known as the smartphone edition), has a 2" QVGA screen, a 200 Mhz TI 850 OMAP processor, GPRS and EDGE connectivity, 64MB RAM and 128MB ROM, and a microSD slot. Users may also like the integrated 802.11b/g and Bluetooth adaptors.
