AT&T Nokia Lumia 900 with the 8779 Tango update
Well after biting the bullet and factory-resetting our Lumia 900 with a ROM flash, we managed to update our glossy-white AT&T Lumia 900 to the official Tango update. That update is sitting in stand-by on Nokia’s servers, presumably waiting for AT&T to give the go to push out to the Zune servers so the rest of you can update.
Although you can manually do this yourself using a third-party program called Nokia Care Suite, you will factory-flash the phone meaning the device will be completely wiped—no saved games, no saved photos. In that regard, you may be best served by just waiting a few days (weeks?) for it to hit Zune where you can just update the phone and keep everything.
In the meantime, we sacrificed for your knowledge. In turn you can watch our video hands on after the break for our thoughts on the update in addition to our mini-review...
