We heard a few days ago that Google will announce the next version of Android OS at Google I/O and the rumors were true. Google officially unveiled the next version of Android OS which is known as Ice Cream Sandwich and its codename is Android 4.0.

Ice Cream Sandwich will offer mixture of Google Honeycomb and Gingerbread. It will be available for all Android device including tablets and phones, which means that both Android tablets and smartphones will run on the same OS. �All devices� doesn�t mean your G1 will also run it.
