T-Mobile USA customers with the HTC HD2 Windows Mobile 6.5 handset may have received a new over-the-air update earlier today, this update brings your handset’s ROM to version 2.13.531.1.
Currently details regarding this update are scarce, we do know that the ROM includes two new applications, these are “My Account” and “T-Mobile Help”, both are pretty self explanatory. “My Account” allows you to check on how many texts and talk-time minutes etc you have left, “T-Mobile Help” shows users tips and tricks as well as offering access to the T-Mobile forums.
If your handset has not yet received the update you can download it manually here, you should then be able to update your ROM with the PDA Phone ROM Update Utility, as always we recommend backing up your date beforehand just incase something goes wrong.
If you have installed the update feel free to let us know what changes you have noticed in the comments section below, for more details check out the source link.
