Lumia 920 in all colors is back in stock at AT&T website, and is available to order online now. Yellow and Cyan colors will ship in 7-14 business days, which indicates that these colors may have been shipped by Nokia but have not yet reached to AT&T. Hope the second stock supply is larger than the first one, as this is “Black Friday” time and AT&T is going ahead with aggressive pricing of $49.99 for Lumia 920 in its retail stores between 23rd to 25th November.
