The Samsing Galaxy Note is supposed to receive Ice Cream Sandwich sometime between March and May, but a leaked ROM is giving some a taste of it now. This ROM is only good for the Chinese variant (GT-I9220). It does not work with the International version (GT-N7000) or the AT&T version that releases this weekend.
This is definitely an Alpha build so expect a lot of bugs, but we hear the camera and Bluetooth are working. We also expect a release for the International version soon so stay tuned.
