Sony Xperia Arc and Arc S

CyanogenMod 10.1 (CM10.1) based on Android 4.2 (Jelly Bean) version now arrives on both Sony Xperia Arc and Arc S, courtesy recognised developer at XDA known as Zackconsole. This ROM is said to be stable while the issues in question relate to Bluetooth and camera (inverted).

Despite a couple of issues, the developer does not recommend users to use this as a daily driver because it is still in its alpha stages.

"Users have reported that it is working nearly as well as the device's CM10 builds, so it may not be very long before the ROM is stable enough to run daily," claims the post on XDA Developers' Forum.

IBTimes UK cautions users to proceed at their own risk and reiterate we will not be held responsible for any consequences.
