Both ASUS and O2 have just released Windows Mobile 6 for several of their devices at the oh-so-lovely cost of $0. If you own the ASUS A639, A626, A686, A696, P535, or P735, head over to the ASUS Support site and select PDA from the Product and Series drop-down menus, followed by the appropriate model number. Updates are available in a number of languages. Lastly, there’s the O2 Xda Zinc. If you own this device, head over to SeeO2.com.
