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 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, and important functions like FM radio and GSM are turned on. However, additional certification and approval is needed before an official upgrade can be released. As previously communicated, we will upgrade all 2011 Xperia™ smartphones running on Android to ICS. Read more to find out what’s included in the beta ROM, and what other limitations apply.
