Earlier this week, we got wind of a new OTA build JOP40G possibly hitting the Nexus 4 soon. I thought this update would finally be the elusive Android 4.2.2 that we've been hearing about, but it looks like that's not the case.
Yesterday, Google pushed some new open source code to AOSP (Android Open Source Project) marked with 2 new tags: android-4.2.1_r1.1 and android-4.2.1_r1.2. The build number corresponding to the 4.2.1_r1.2 release is - you guessed it - JOP40G (with mentions of JOP40F and JOP40E along the way too) - the same one we thought would be 4.2.2.
