Sprint Windows Mobile 6.1 ROM has surfaced for the HTC Mogul (aka Titan). At CTIA Sprint vowed to upgrade many of their devices to the new version of WM, and the Titan is the second to receive the upgrade after the now discontinued
Motorola Q9c. An upgrade for the Touch is expected soon, and the
Treo 800w will ship with WM 6.1 in a few weeks.
