In case you haven’t heard, the first devices to run Android 4.1 Jelly Bean following the launch of the Nexus 7 tablet are those Android handsets and tablets that run a vanilla Android build, one the Google can update itself without the help of device manufacturers and carriers. These devices include two smartphones and a tablet: the Samsung Nexus S, the Samsung Galaxy Nexus and the Motorola Xoom.

And it so happens that Android users who are members of the Motorola Feedback Network and own the Wi-Fi version of the original Xoom have received invitations for a software test. The most logical conclusion is that we’re looking at the Jelly Bean soak test, although neither Google or Motorola officials – technically they’re also Google employees – are confirming the Android 4.1 update for the Motorola Xoom.

At the same time, we’ll remind you that international GSM Galaxy Nexus units have already started to receive their Jelly Bean upgrade, which means we shouldn’t be surprised to see Google roll out its latest Android version to supported devices as fast as possible.

Have you received such a soak test invitation?
