I just upgraded my phone to 4.0.4 and got SmartGlass to work on it, i must say it's fairly nifty. I'm not amazingly impressed yet, but we'll see what happens.
The only problem I have is the main use so far (to control your Xbox) doesn't feel right. I want the option to change it so i move right by swiping from right to left, like I would on almost any other app on my phone. I'll adapt like I always do, but y'know.

Anywhoozle, it's neat.
