Sony Mobile has released Android 4.0 (Ice Cream Sandwich) beta ROM for unlocked Xperia PLAY smartphones. They released ICS beta ROM for Xperia arc S, Xperia neo V and Xperia ray last month. They have also announced they work close with several game partners to optimize the games to run on the latest Android 4.0 software. They also want the users’ feedback on how several games work on the beta ROM.
This is not a finished version, hence it might not be stable. This version doesn’t include the Google Mobile Services (GMS) apps such as Face unlock app, Gmail, Google Maps and Wi-Fi, but this would be available in the final version of the ICS that would be rolled out to 2011 Xperia smartphones soon.
The Android 4.0 beta ROM is available for Xperia PLAY running the latest Xperia software (4.0.2.A.0.42), and you also need to unlock the bootloader for these phones manually.
