The official Samsung Galaxy Note Android 4.0 update rolled out earlier last week in certain parts of Europe. So far, the verdict seems to suggest that there are no bugs and it brings a host of new improvements to the already feature-rich Samsung Galaxy Note.
Samsung Galaxy Note Android 4.0 Ice Cream Sandwich update: how to get it right now
Unfortunately, the rollout of the Samsung Galaxy Note Android 4.0 Ice Cream Sandwich Premium Suite update is staggered and the update appears to be available to some regions in Germany mainly at this time. However given that it is for the GT-N7000 model which is the international GSM Samsung Galaxy Note and is used all over Asia and UK as well, it is technically compatible with many Galaxy Note units.
If you happen to have a Samsung Galaxy Note GT-N7000 model (you can check by rebooting your Galaxy Note as the boot animation will clearly state your model number), then you can now trigger the update yourself.
The folks over at XDA Developers forums have prepared a concise instructions guide on how to do it. Do note that you will need to root your Samsung Galaxy Note to accomplish this so only proceed at your own risk.
