from the specification of the HD posted on HTC site:

I don't see that there is a band that will work in the US.
Or let me explain it this way the WCDMA is 900/2100 MHz but Sprint's CDMA is 850/1900 MHz.
In other words, no, it will not work, beside it is GSM so far, hopefully they will come up with CDMA one soon, and if I am not mistaken I think I read some where that Verizon is getting it soon, but I can't recall where was that posted, so I would say wait a little bit, you might be pleased later
Good luck
