'tis only for the Legend (unless he's done a Desire version), it's just a modified HTC Sense 2.2 Rom.
He's sped it up god knows how, changed the font and slipped in the Circle battery mod and some other graphical changes. I used an earlier version which was good, but not this good. It makes CM look slow!

Just set minimum underclock to 122Mhz and max to 806Mhz - will see what the battery life is like with those settings, I'm hoping a bit better as it should be underclocked most of the time and only raise to 806Mhz when it's needed.
