I have been waiting for a while for the Windows Mobile 6.1 upgrade for the HTC Touch (Alltel), and finally HTC (Alltel and Microsoft) have released a 6.1 ROM upgrade.

The main problem with the mobile companies is that they all have slightly different implementations of Windows Mobile (WM) 6.1 based on the individual carrier requirements, as a result you cannot blindly update your phone with an off the shelf version of WM.

HTC and Alltel appear to have been very quiet about the upgrade, and I found out about its release by accident, to further the confusion it appears that the 6.0 upgrade will only be available for free until October 31st, a mere 3 weeks after 6.1 became available … very strange.
