Android 4.2.2 firmware (10.3.1.C.0.136) finally released for Xperia Tablet Z Wi-Fi

The Wi-Fi versions of the Xperia Tablet Z,  model numbers SGP311 and SGP312, are finally seeing the Android 4.2.2 update.  Firmware build 10.3.1.C.0.136 is the update rolling out to select regions right now. The LTE Android 4.2.2 build rolled a while back now so it’s good to see those with Wi-Fi tablets on equal footing.

Thanks to all that sent this in!
