Though both have had less-than-official upgrades floating around for ages, Sprint and HTC have finally seen fit to bless the Touch and Mogul with the real deal. In the case of the Touch, the Windows Mobile 6.1 update includes Sprint Navigation, EV-DO Rev. A, integrated Opera, and a new on-screen QWERTY keyboard, so it seems more than worth the few minutes you'll spend downloading it and getting it all going. The Mogul gets Sprint TV (yay?), but unfortunately, no patch to magically morph it into a Touch Pro. Seriously, we'd pay good money for that.

Update: It looks like they've been pulled for the moment, but keep a keen eye out at HTC's support site -- we're hearing they could show up again next week.
