Reports of the OTA arriving are coming in fast and furious
The 4.3 OTA for the Nexus 4 seems to be rolling out en masse, as I'm getting reports from everywhere that it's now available. To check for the OTA yourself, open Settings, scroll down to About phone, and tap the System updates line item.
If you're just not having any luck, the link location has been uncovered. You can download the OTA for manual side loading right here. If you need any assistance, head into the forums and holler.
Happy flashing, and enjoy your new flavor of Jelly Bean!
Thanks everyone who sent this in!
