Having heard Orange's news that the Samsung Omnia 7 would be HD Voice compatible on their UK network, we chased up HTC to see whether the same was in store for the HTC 7 Mozart. Unfortunately, it seems Mozart owners will have to make do with regular audio quality; HTC has told us the company has "no plans" to add in HD Voice support to their Windows Phone 7 smartphone.
Right now that's no great loss, given the relatively small scale of HD Voice in the UK. The feature is currently limited to a handful of Nokia devices and the Samsung Omnia Pro, and can only be used on the Orange UK network. Still, if the carrier's plans to promote HD Voice as a generic standard pan out, it could be an interesting differentiator between otherwise relatively similar Windows Phone 7 devices.
