Finally, we get some Android 4.2 OTA updates on devices out there that are not Nexus related. ASUS is starting to roll out some upgraded Jelly Bean to their Transformer Pad line. First one to get it…Transformer Pad TF300. This update is only for US users as of now, with other countries getting it towards the end of March. This update includes updates to App Locker, Virtual Keyboard, Lock Screen and Setup Wizard applications, as well as getting those added 4.2 features. Shortly after Pad users receive this update, ASUS plans on getting Android 4.2 to their MeMo pad line, as well as their Transformer Pad Infinity. So if you own a Transformer Pad TF300, you will soon be cooking with butter. Keep checking your system updates, and let us know if you have received it yet.
