UPDATE: Looks like devs and early adopters have managed to work it on GT-N7000. However, tread with caution. XDA-Dev
We have seen quite a few Ice Cream Sandwich ROMs leaked for Galaxy S II but this is the first time we’re seeing an Android 4.0 ROM trickle out for Galaxy Note. The leak originated on a Chinese forum and is compatible with Galaxy Note with model number GT-I9220. To be clear, I9220 is the Chinese variant of Note and won’t work with the international version of Note, which is GT-N7000.
This is a leaked and apparently an alpha or a beta build, so don’t expect everything to run butter smooth. However, camera and Bluetooth reportedly work fine.
