I just got an update notification yesterday. After the download (approx 8.8MB), the phone just rebooted without applying the update. I can't get the update to download again.
Got my GNex on Jan. 12. It came with a Samsung ICS build 4.0.1. Unlocked bootloader and flashed the Google ICS build 4.0.1. Upon rebooting, the phone updated to 4.0.2

I flashed mine last night to the yakju build and got the update in about 5 min. It's very easy to do. Google wallet works also after updating to 4.0.2.
