Any news on the speculation that the Atrix 2 uses a ST Ericsson M570 radio?
Maybe we can get something useful out of Sony's recent ICS beta builds for Xperia phones? (http://androidcommunity.com/sony-offers-official-ics-beta-roms-for-xperia-arc-s-neo-v-and-ray-phones-20120223/)
Ooohh! Nicely done, Sony.
