ICE aka Android 4.0 has a completely different interface as compared to Android 2.x series. It's not radically so different that a user will be confused, but it does come with a lot of cool new features and it's better if a user knows about it. Since Samsung has started rolling out ICS for its Galaxy S II users in Europe it has become important to help such users to get started with their brand new OS. Samsung has released a guidebook to help such users. The guidebook explains in details all the features of the new operating system and how you can interact with your phone once upgraded to ICS. Coolsmartphone has put together that guide in form of a PDF which can be easily downloaded or printed. I wish Samsung has done the same.
