An Ice Cream Sandwich build for the Galaxy note has surfaced on a Chinese forum, marking one of the first chances for Note users to get their hands on an early build of Android 4.0. The particular build is geared towards a Chinese variant of the Note, the GT-I9220, and is not directly compatible with other models.
The build is said to be an alpha or early beta with many features still lacking. Bluetooth and camera support are present, however. Recent rumors have the Note and Galaxy S II receiving ICS in March, but from the looks of the build it could still be a bit of time before we see the new OS on the 5.3-inch screen of the Note (assuming the leak isn’t outdated). There is already an XDA thread for those interested in following development of the build.
