It looks like Samsung is pushing ICS to Galaxy Notes everywhere. The newest country to get it is India. It’s available as both an OTA or through Kies software from a computer. It’s great to finally see Samsung using OTA updates for models outside of the US. Most of their older phones needed Kies to be updated, meaning having to tether your phone to a computer. OTA is a much more pleasant experience.
You should check for updates in Settings to see if you can get the update now. While the update doesn’t look too different from Gingerbread, thanks to TouchWiz, it still carries many improvements and performance tweaks. Try out the new S apps, like S-Note, as they have been redone with more functionality. And tell us how the update goes!
