I tried that, too, but I think the biggest problem was activesync was disconnecting.

The UPDATE here is that I was poking around on HTC's site and in the software downloads section it said "Tip: If you are having challenges connecting with ActiveSync, please try: Start > Settings > Connection Tab > USB to PC > Deselect Enable advanced network functionality. "

Once I did that, it seemed to work! Now my problem is that it hangs on boot. But, HEY! It's progress!! and fun too!

The BuildOS program splashes a box that if you have this problem to take out the battery and put it back in, then do a hard reset. I tried that, but it hangs on the splash screen "PPCGeeks and PPCKitchen.org present" with the Swedish Chef in the bottom left. I tried taking the battery out and a hard reset twice...still hangs.
