got the HERO os on my android with apps2sd and swap ext4`
the mytouch doesnt have the hspda frequency for Att that is why its on Tmobile u maybe getting EDGE, could be wrong on that bo who knows.
HTC RIM GOOGLE and a few other dev, developed this os. under google's company. it is by google for the venders
Only problem is with phones like the Hero and some Magic's are no OTA updates. It has nothing to do wither it has Android OS or not.

The Sense UI is sweet, I think I might toss it on my Magic tommorow.
