HTC’s support site is in a state of flux for the AT&T Tilt (a version of the HTC TyTn II).  The page is fluctuating between having a description for the Windows Mobile 6.0 ROM and the Windows Mobile 6.1 ROM.  Regardless of which page is displayed the Windows Mobile 6.0 rom is always the target of the download link.  I sent a question to their support department about this and they say the firmware update will be available by the end of the month.  Happy Days are Coming.
