For those that don’t know, the CyanogenMod 10 Alpha was released for the 2011 Sony Xperia handsets recently. We had already seen CM10 pop up for the Xperia S, but was waiting for some Jelly Bean action on the 2011 handsets. These are alpha releases so therefore they are not recommended to be used for daily use, however feel free to give it a try to see how well fast Jelly Bean will perform on your Xperia device. See the full list of links to the CM10 ROM below.
