It seems that HTC HD7 and HTC Mozart owners from around the world, such as India, Switzerland and Poland are reporting that internet sharing works. It will be interesting to see if T-Mobile will be approving this update, since internet tethering in the US generally requires a fee, so there might be some complications on that end. The update also brought about performance enhancements, so if you’re still holding onto your HTC HD7 or HTC Mozart, plug it into your computer, fire up Zune and start the internet sharing!
