AT&T subscribers with Lumia 820 and 920 smartphones have had to wait a long time to get their Nokia Amber update, but it's at last on the way. The carrier tells customers in its Community Forums that the upgrade should reach their handsets starting tomorrow, October 10th. Much like the many preceding rollouts, AT&T's Amber release should add a slew of camera tools, double-tap to unlock and other extras that have been shipping with more recent devices. As long as you can resist the siren's call of shiny new hardware in the days ahead, you'll likely be happy with the new software.
