Remember when you were younger, and your Mother forced you to spend your Saturdays trying on clothes instead of watching cartoons? You knew exactly what you wanted to wear - your PJ's - but thanks to Mom, you had to go out and get normal clothes. Keeping that in mind, I kind of symphathize for the HTC Touch Pro2. Two days after it was trying on Ubuntu for size (instead of the stock Windows Mobile), it's back again with Android in tow.
As with most "installations" of this nature, a few things aren't working properly - in the Touch Pro2's case, GPS, Bluetooth, and "other key functions." Despite that, the essentials (calling, messaging, browsing) are working well. I've often wished that there was an Android variant of the Touch Pro2, so for those that feel the same as I do, this might be your opportunity.
Take a look at the video below, and if you feel comfortable with it, give the install a go (at your own risk, of course)!
