I thought it would be special with the nexus on 4.2.2? Sorry for my noobness but on the iPhone if you updated there was a new procedure to do every time so I am just a little confusedthe tl;dr version:
1. Install SDK
2. Make sure you have fastboot
3. Reboot to bootloader
4. Plug in phone
5. Open terminal
6. fastboot oem unlock
Same as with any other Nexus.
Also: see this excellent guide. http://forums.androidcentral.com/nexus-4-rooting-roms-hacks/224861-guide-nexus-4-unlock-root.html
