FYI: There is a thread here about rooting the Rogers HTC Magic and Dream: Rooting rogers htc phones?
Thanks to itsolution42 for the link (itsolution42 is also a follower of the IWantMyOnePointSix twitter feed).
Just because it has to be said: Use the instructions, and root, and your own risk. I have not tried these instructions yet, and your results may vary from others. You could brick your phone if you are not careful, and it voids your warranty. Caveat Emptor, consider yourself warned. I'm not a lawyer, or a doctor, but I occasionally play one or both on TV. Not.
