Today we release an Ice Cream Sandwich (ICS) beta ROM, as a follow up to the previously released ICS alpha ROM.
In line with our goal to support the open XDA developer community, we want to give you the chance to try out our coming upgrade to ICS (Android™ 4.0) in this beta version. While the ICS alpha ROM was an early preview, the ICS beta ROM have passed some certifications such as Modem type approval.
As with the alpha release you should have an unlocked boot loader http://unlockbootloader.sonymobile.com, and have the knowledge to switch between different ROMs.
Find the links to download the packages at Developer World.
Again we appreciate your feedback on the beta ROM in this small survey. Some of the improvements in the Beta release compared to the alpha release:
• Updated UI
• Updated Widget picker
• Connectivity turned on
• Updated email client
• Added quick dial
Lastly, we do follow the comments and new threads posted at XDA and we will very shortly release the open source archives for custom ROM community. I know the FreeXperia team working on CyanogenMod have made lot’s of progress on their custom ICS ROM and we try to support the team within the frames that we are allowed to operate.
