Cyanogen Mod 10 (CM10) is hot now in the market because of the Jelly Bean Android 4.1. CM10 is build based on the latest Android 4.1 Jelly Bean Stock ROM and finally CM10 Jelly Bean has came to my lovely Samsung Galaxy S3 i9300 International version. This is the official CM10 ROM and brings mostly all the Jelly Bean Android 4.1 features like smoother interface, better keyboard, enhanced notification bar and a lot more. However, this is still a preview build, but it is close to daily use version. See the working & non-working list and install guide after the break.
