The long-awaited upgrade to Jelly Bean has finally arrived for Rogers Galaxy Nexus customers today. A notification for OS 4.2.1 should have popped up for you, but if not make sure you hit Menu >> Settings >> About device >> Software update >> Update.
Update: TELUS and WIND Mobile Galaxy Nexus users are now reporting the Jelly Bean is available to download on their devices.
(Thanks Matt, Patrick & to everyone who sent this in!)
