Finally, you can upgrade seven Xperia devices to Android Jelly Bean through CyanogenMod 10. The seven Xperia devices are coming from 2011 specifically they are Sony Xperia Ray, Sony Xperia Neo/Neo V, Sony Xperia Arc/Arc S/Pro, and the Xperia S.
This is a continuation of a previous project which the Xperia S lock screen has already ported to five other Xperia devices, while ICS AOKP successfully ported to 16 Xperia devices too. Therefore, this week Sony Xperia line up has been rather busy. If you like to do something with your Xperia device, you had a lot to do with it.
But the CM10 for Xperia devices are not highly recommended for day-to-day use since it still in Alpha version which needed a lot of work to get the stable version.
The CM10 alpha builds mean there are many bugs listed on the ROM with not working item around them. There is no list in the thread that lists the bug but you can track each ROM to find out what exactly what’s wrong. However, some users have reported that at least basic features have been working such as network, WiFi, camera, and a few other features. But we still highly not recommended to flash the CM10 ROM into your phone for daily use but if you would like to know how Android 4.1.1 Jelly Bean works on Xperia devices, it is definitely stable enough to enjoy by exploring them on your Xperia phones.
