Not for nothing folks, but I've been coming through all the technical documents available and one thing that strikes me funny is one simple fact: Goto HTC's site and they list the Mogul as EVDO Rev A upgradeable. They do not list the Touch as upgradeable. Even though it might be the same chipset, sometimes all it takes is not soldering a particular pin on a chip to disable a feature. I use to design electronic products and we did that all the time for OEMs.
One other thing I found fascinating is this little blurb on page 173 of the Touch User's manual:
"GPS: Internal GPS antenna"
Have fun with that one
