Some of us are at January 12, 2013...time traveling. ; )
Interesting. I have a usual timeout of 24 hours on my GN2.
For every update I attempt I must wait 24 hours to try again.
I attempted to get the update at around 9:15 AM CST today and got nothing.
All I did was go into the date/time settings, turn off auto update from network, bump the date up 2 days, then immediately checked and got it.
If it is not working for others, it sucks, but it also makes me wonder how our handsets/markets differ that they would behave differently.
I was running the stock AT&T 4.1.1 build you get out of the box. No root.
