A few weeks ago, we learned of an update on its way to several Windows Phone models, including the HTC HD7 in Europe. Although we thought the release would be geographically restricted, some HD7 owners on T-Mobile in the States did report successfully being able to update. If you weren’t among them, and have been waiting for your own chance to get at the new software, a leaked screenshot from T-Mobile’s computers reveals plans to deliver updates to both the HD7 and Radar 4G, starting tomorrow.

The big news for the HD7 is the addition of support for Internet Sharing, turning your Windows Phone handset into a mobile hotspot. There’s also the fix that will now let you connect to invisible WiFi networks, if you’ve been taking steps to keep your WiFi access point low-profile, as well a patch to correct problems accessing visual voicemail.

The Radar 4G’s update isn’t nearly as interesting, but will still include that visual voicemail bugfix. Beyond that, all we’re expecting is new support for ringtone downloads and customization.

If all goes to task, both updates will be available tomorrow; better get Zune fired-up and ready to go.
