You all remember how we told you about a certain colorful, yet buttery test run that was imminent for certain Motorola Xoom owners? Well the test run has begun and according to our sources, the new update is being pushed to owners of the device which confirms what we already knew, Jelly Bean is officially on the Xoom WiFi. The update includes the latest Jelly Bean version (Android version 4.1.1) and the software build for the Xoom update is known as JRO03H and comes in at 79MB. While it might be too early to call, our source confirms Android 4.1 does have a slightly tweaked appearance like new fonts in addition to the smoother transitions in the UI. It looks like Jelly Bean has gotten a new lease on life with the 79MB update! No word yet on when the formal release will be pushed, but it looks like it won’t be too long before other Xoom owners get that Jelly Bean lovin’.
