So, what is the HTC CONV100? Looks like we might finally have our answer after the freakin' Bluetooth SIG left us all scratching our heads a few months back. The answer lies in this grainy picture that the FCC somehow passes as an official filing document, in this case used to identify the location of the Bluetooth antenna relative to the exterior of the device. Those with sharp memories will recall that this looks suspiciously like the spy picture we saw of the supposed Shadow II for T-Mobile, and the lack of WCDMA 850 / 1900 in the test documentation would certainly jibe with that theory. The white casing looks like it could really pan out, too, so we're kinda hoping T-Mob ends up offering at least a couple colors when this one inevitably gets official in the next few weeks, months, years, or decades.
