A. I'm amped up about the Touch HD, as well. So far there's no word - or even whispering - about a US carrier.
I know HTC is interested in bringing the phone to the US and will do so at least in an unlocked version, but that won't be until sometime in 2009. What I can tell you is that over the past year or so Sprint has been getting most of the HTC phones first in the US - Touch, Touch Diamond, and (coming soon) Touch Pro all went to Sprint first. So if I had to bet I'd put my money on them. Although T-Mobile is going to be stepping it up with the launch of their 3G network, and they don't have an iPhone/Instinct/Dare all-touch device yet. Maybe Touch HD on T-Mo? You never know. I'll keep you updated on the site as soon as I find anything out.
