One incarnation of the HTC Raphael will be called the T-Mobile MDA Vario IV.

In terms of looks, this is first full quality of the Raphael (in any guise) that we have seen.
As I say, this is in fact the rebranded T-Mobile version of the Rapahel and going on how this compares with the MDA Compact IV (HTC Diamond), we can expect the actual Raphael to be very similar in appearance to the HTC Diamond.
The unofficial release date is Q2 2008 (within one month then) and the specs as you'd imagine the same as the HTC Diamond, but with a slide-out full qwerty keyboard and an extra 48 grams.
This version probably will not reach the US shores, but do expect the HTC Raphael coming from Sprint.
