Introduction

Google's newest and best version of Android just became official at the Google-Samsung event in Hong Kong along with the Galaxy Nexus. And although it may seem like it, Ice Cream Sandwich is not just another update to Android but a way to curb some of the inherent issues with the OS, such as fragmentation, that have been plaguing it for a long time.

Ice Cream Sandwich combines the tablet optimized Honeycomb and Gingerbread into a cohesive whole. The unification of the UI and APIs means that developers will no longer have to worry about multiple devices and hardware configurations and just have to develop their apps for one OS and it will automatically work perfectly across all devices. This is what Google promised us at their I/O event when they first announced Ice Cream Sandwich and that is what they delivered today.
