Even though it’s certain that Motorola’s Droid RAZR will be one of the first devices to get upgraded to Android 4.0 Ice Cream Sandwich, but it seems Android developer “DroidTh3ory” just couldn’t wait that long.

He already has Ice Cream Sandwich working on his RAZR but the performance is anything but stable. The custom ROM is currently not public. We’re don’t know how long it’ll take DroidTh3ory or Motorola to push the update, or who will out do the other. You can have a look at the video to get a fair idea of what works and what doesn’t, but we warn you don’t expect much out of this.
