Notion Ink has recently released the Alpha version of Ice Cream Sandwich operating system for its Adam tablet. As it is still an alpha build, there is quite a number of features that aren’t working yet, such as the 3G, camera, USB, light sensor, HDMI sound, and more.

The alpha build is not recommended if you want to use your device everyday, but if you still want to have ICS on your tablet, you can download the update and give it a try. Don’t forget to back up your data before following the instructions carefully!
