In very similar Nexus news to what we found this morning, the Nexus 4 is now beginning to receive the 4.2.1 update as well. This update most notably fixes the infamous December bug. No other changes have been uncovered as of yet. The good news is that the baseband has remained unchanged so far thus still allowing LTE capabilities for the select few. This update will be come by way of over-the-air so obviously not everyone will get it at once, but it should only take a few days for it to roll out to all devices. Are you a lucky owner of the elusive Nexus 4 that has also received the update? Let us know of any other changes you may find.
