Not to be outdone by ROM leaks and unofficial copies of its Windows Mobile 6.1 update for HTC TyTn II handsets, HTC has gone official with their HTC TyTn II ROM-boosting update. HTC has delivered 
the ROM update to keep their flagship touchscreen handset at the top of its game, and at the same time appeased the masses complaining of crippled video performance.
Threaded SMS, “Getting Stated” wizard, improved video performance (finally), more efficient power draw (read: better battery life), and overall faster performance are all pieces of the Windows Mobile Professional 6.1 package. And, seeing as how the update is free, there’s no reason why anyone shouldn’t hop on board the WM6.1-train.
HTC has made their Windows Mobile 6.1 ROM for the HTC TyTn II (Kaiser) available through their e-Club webpage. Unfortunately for AT&T Tilt customers, they’ll have to wait for Big Blue to get with the times and release an update for the AT&T-branded version of the HTC Kaiser.
