One thing which am sure you must have faced with the release of new firmware updates is its unavailability in many parts of this planet. Apparently its not Nokias fault that everyone doesnt get the firmware update at the same time.

From Nokia FAQ:

Please note that your mobile service provider, operator, or carrier may not have approved the latest Nokia device firmware available.

Nokia produces many different variants of each product (for different countries and languages) and not all variants have the latest Nokia device firmware. It is our priority to update all variants as quickly as possible, and we apologize for any delay. New software may become available at a later date, however, so please check back soon.

The best thing you can do is go to Nokia Softwate Update Checker and check for your device specific updates. Mostly you will get the new firmware after 7-10 days of its release.

Hope that helps.
