Samsung has made it official that its popular Galaxy Note will be getting the Android 4.1 update in a couple of months but now android developers at xda have churned out a CM10 release for it. Keep in mind that it is just a preview and lot of features are not yet working currently. Here is a screenshot just to prove that we are not lying.
Earlier, we talked about CM9 on Galaxy S3 and then later on, Mobilityupdate found a preview build of Cm10 for Nexus 7 Google tablet. Keep note that it is your responsibility to flash such experimental firmwares on your expensive Galaxy note tablet. To be on the safe side, make a backup of everything before you proceed.
