Dunno if this was posted before, but it seems the MyTouch 4G (HTC Glacier) uses the same battery as the Thunderbolt. I haven't tried it myself, but a lot of places are selling "Thunderbolt" batteries, when they're just MyTouch ones.
This is good to know if you're shopping around for an extra battery at a good price. I prefer an extra standard battery to the bulky extended one.
