Just as we expected, HTC has let us know that they've released the Windows Mobile 6.1 update for the TyTN II. That's the first official Windows Mobile 6.1 upgrade available on any device, meaning that along with the Touch Dual, HTC is selling the only official Windows Mobile 6.1 devices at the moment.
Just to reiterate, that update is only available to folks in Europe who have the straight TyTN II. As for 'branded' TyTN II devices like the HTC Tilt, there's going to be wait, as “[HTC looks] forward to providing similar updates for certain carrier and HTC-branded devices in the near future.”
We look forward to it too, HTC, and hope that future is indeed near.
