The long, cold wait for an official HTC TyTN II Windows Mobile 6.1 build will soon be over. According to several sources, HTC is in the final stages of preparing an official firmware update. The revamped OS will be made available for HTC branded devices sometime over the next several days, with an AT&T version for the Tilt coming sometime after that. Nothing unexpected in the actual update, with threaded SMS, a Getting Started Wizard, and modest performance improvements topping the list of changes. We’d still recommend loading this one up, however, so stay tuned for the upcoming official launch.
