It seems Samsung has started rolling out the Ice Cream Sandwich update for Galaxy Note (N7000). Few users have started receiving notification for the firmware upgrade that will bump the Android to version 4.0 and bring in the Premium Suite apps.
Samsung firmware updates are generally released region-wise so you may have to wait a bit more to receive the notification.
UPDATE 2: The XDA Developers thread has revealed few more details. Its the XXLPY Android 4.0.3 build with a build date of May 4.
UPDATE: Its available for German Note users via Kies as well.
