Running it on my Atrix now. Using CM9. Waiting on camera functionality though, but I can deal. My phone runs amazingly smooth now. Sphere transition on GOLauncherEX used to be very sluggish, w/o Blur and with better use of dual core it works as nice as on the SGS2. I use the Trebuchet Launcher though, for that ICS look. Trying an update in a couple minutes that should give me back my fingerprint reader.
