The advantages of having a Google flagship device. It is a developers dream. I do not even know why they bother locking the device up at all. Should just come already unlocked, and ready for a custom ROM. Over on XDA, a developer by the name of mskip, has got the first toolkit version for the Nexus 4 ready to download. It offers help on unlocking the bootloader, rooting, and tons of other stuff you will need to make that new phone rock even more than it already does. Only available for Windows, so head over to the XDA forum page and grab a download. Let us know how it works.
