1. there's no way to change the interface past the color of the tiles and they are actually quite vibrant and useful. makes it look more alive sort of speak. this interface will also be implemented in the new Xbox dashboard and the upcoming windows 8 so the tiles are here to stay.
2. no possibility to run xdandroid but there is a possibility to run the mango beta that has been leaked. I loaded it onto my arrive today and it is impressive.
3. yes there is. check the disassembly thread by @
pbankey and @
steveo70 and @
