HTC Mozart Windows Phone 7 phone headed to T-Mobile?

So is it the HTC Mozart, HTC Schubert or are they both the same device like I’ve always thought? According to TMONews’ sources the HTC Mozart Windows Phone 7 handset is headed to T-Mobile US this fall. We first heard about this device a few weeks ago when it appeared in an internal Telstra document and we also found out its user agant string on HTC’s server just a few days ago.Now what is interesting here is that the leaked T-Mobile roadmap that popped up 2 days ago only mentions the HTC Schubert WP7 device. So are they both the same phone (like the HTC Mondrian, HTC Gold and HTC Spark…)?
