You haven't cracked root on your Android phone yet?
2) For many Android devices (kit from MOT excepted), the hacks are pretty trivial. I suspect the protections on HTC phones are more of a "Warranty void if removed" sticker than something to really bar you from gaining root.
AT&T (and perhaps other carriers) disable that option, but even in that case, there's a workaround that doesn't require rooting. (Google "android non-market adb".)
This is useful, and I think more of what the OP was looking for.
