Over the weekend, a couple thousands WiFi XOOM owners began a soak test of Ice Cream Sandwich. It didn’t take long for the update file to leak and almost everyone began loading it onto their XOOM. And now, the official OTA has begun rolling out to all WiFi Motorola XOOMs.

WiFi Motorola XOOM owners may be in for a treat. Motorola has begun sending out invitations asking “Google Experience” XOOM WiFI owners to participate in a new project. They go on to inform users that the project is confidential and that you must first meet certain requirements to partake in this particular project. It’s all very mysterious, but given the fact that they specifically refer to the XOOM as a “Google Experience” device, it’s highly likely that they are preparing to release the Android 4.0 update and are looking to test it out.
