Symbian Anna v25.007 firmware update is currently rolling out via Over the Air (OTA) for Symbian^3 Smart Phones (Nokia N8, E7, C7, C6-01, E6 and X7). The previous version was 22.014. This update seems to fix some of the minor bugs. Official change-log has not yet been released so far. The update may not be available to all the regions. The variations in availability are because of the huge variety in operator, country and language versions and the testing/approvals needed, plus there is some device dependency too. You can let us know via comments whether this update is available in your region or not.
