Sony is interested in user feedback after posting an initial beta Ice Cream Sandwich ROM for the Sony (Ericsson, back then) Xperia Play. They’re especially interested in how well all those games are working with the new Android platform.
If you have an unlocked Xperia Play phone and want to give the manufacturer (and the community) a helping hand, you might want to try out the firmware (if you’re into that). For more details and installation instructions, follow the source link below where you will also find information on how to send feedback regarding games and their operation on Ice Cream Sandwich. However, Sony acknowledges that “when it comes to Xperia Play, we do know that some games will need to be optimized to work fine with ICS”.
