The Inspire is such a sweet phone
Indeed, the only US major carrier version of the Desire HD with NO changes
AT&T crapware is on board and many removed native Sense apps such as Locations are removed (HTC's premium navigation, better than Google Nav)
But its essentially what the ThunderBolt is, minus the design and some software and hardware specs (kickstand / srs speaker behind the kickstand)
Inspire has SRS but its not as big as the speaker on the ThunderBolt, but also the ThunderBolt isn't made from a single block of aluminum like the Inspire is
so both phones regardless of the carriers are excellent, not to mention there built by HTC.
another nice thing about the Inspire, its compatible with ALL the Desire HD accessories, including that car dock that was just announced in Europe as well for the Inspire. it even fits all the same cases.
Speaking of cases, I received my Seidio Innocase II for the Thunderbolt today, and i must say the construction is better than the one i got for the Incredible, it even has a better rubber feel for grip, and the cutouts are nicely done and smoothed out.
then I checked there website this morning, they have pictures of the Innocase Active X
