I’ll take this as Google’s admittance that the glass backing of the Nexus 4 wasn’t the best idea. Following the release of the white Nexus 4 on Google Play along with a complimentary free bumper case to match, the black version is also following suit. (Update: Yup, it was always there, just looks like Google is now advertising it on their front page).
Hop onto the Google Play Store and you’ll find the black Nexus 4 — complete with matching bumper case (a $20 value) — for the same low $350 16GB, or $300 8GB version. Google says while supplies last and if we know Google, they always seem to be light on supply.
