Hopes that the O2 XDA Zinc would be available this month have been dashed. The O2 UK web site now shows the XDA Zinc as coming in March 2007.
Touted as having all the PDA features and discreet design of the XDA Mini S but with added 3G power for high speed Internet and video calling., the XDA Zinc Pocket PC Phone is powered by a 520MHZ Intel processor and comes with a slide-out QWERTY keyboard, tri-band GSM/GPRS and WCDMA support, 64MB RAM and 128MB ROM, a miniSD lsot, a 2.8-inch QVGA screen, 802.11 b/g Wi-Fi, Bluetooth and both a 2MP camera and secondary VGA camera for video calls.
