The Android 4.2.2 update for the Nexus 4 is rolling out to users, bringing all the bug smashing goodness you can handle to the latest Nexus phone. It's build JDQ39, just like we saw for the other Nexus devices and checks in at about 54MB. If you're curious about what this update brings you can have a look here.
If you don't feel like waiting, you can download the OTA package direct from Google right here and install is manually via a custom recovery or by sideloading. If you need a little help with that, I'm sure someone in the forums will be happy to give you a hand.
Update: AnandTech's Brian Klug notes that it appears LTE Band 4 -- was never supposed to be officially supported by the Nexus 4 and was more of a residual effect from the hardware, which basically is an LG Optimus G -- appears to be kaput.
