Today's the day the Nexus 4 goes on sale, but if you're a Galaxy Nexus owner not quite ready to upgrade to Google's latest flagship phone, don't worry — there's still something to look forward to. We're seeing evidence and tips of an over-the-air rollout of Android 4.2 for the Galaxy Nexus, although it appears to be limited to certain users of a certain variant: the unlocked HSPA+ model that was made available through the Google Play Store earlier this year.

However, Phandroid points out that if you're comfortable with flashing a ROM yourself, you can download the necessary files from Google right now. We've contacted Google for comment on when the latest version of Jelly Bean will be made available to other Galaxy Nexus handsets, but it appears that you shouldn't have too long to wait.

Update: Android Police has download links for the Nexus 7 as well, though it's not clear if Google has started pushing out over-the-air updates to the 7-inch tablet just yet.

Update 2: Nexus 7 updates appear to be rolling out, as well, but if you haven't gotten the notification yet you can prompt it manually with a few simple steps. First turn off Wi-Fi, then go to the Apps list in Settings, select Google Services Framework under the All column, clear the cache, and tap "Force stop." After that, turn Wi-Fi back on again, go to System updates in the About tablet under Settings, and you should be given the option to download the update.

This has worked for us across multiple Nexus 7 and Galaxy Nexus devices, though we occasionally had to clear the cache and force quit Google Services Framework twice.
