In its fray of iPAQ introductions today come two new phones from HP -- the first since the rather bland 510 -- potentialy throwing the once-dominant Windows Mobile force back into the hunt. First up, the 600 series Business Navigator comes equipped with integrated GPS, a generous 2.8-inch touchscreen, 128MB of RAM, 256MB of ROM, 3 megapixel autofocus cam, WiFi, and Windows Mobile 6 Professional, all sitting atop a Marvell PXA270 putting along at 520MHz. The 600 rocks a numeric keypad; a dealbreaker for some, yes, but the nifty touch-sensitive scroll wheel integrated into the keys may be enough to sway a few back. The 900 series, meanwhile, swaps out the numeric pad for a standard QWERTY outfit and steps down to a 2.46-inch display, but the specs remain otherwise similar to its stablemate. Look for both to ship before the year's out.
