Last month, the Lumia Black update was rolled out by AT&T to the users in US but the rest of the globe still has yet to receive it. For China, they will get the update next week with other countries to follow sometime in the first quarter of this year. This brings Nokia specific additions on top of Windows Phone 8 Update 3 in which it has some exclusive apps and usability tweaks in addition the Update 3's enhancements. The Chinese version will have Call Blocking and Application folder in addition to Glance screen, Nokia Camera and Storyteller apps, RAW support and Bluetooth LE 4.0. Perhaps the rest of the globe should also have the Call Blocking and Application folder as well as these features are somewhat common.
Well, if you do have Windows Phone 8 Update 3 preview as released in October last year, you can get the Black update sans Update 3 as noted by Paul Thurrott.
