Nokia store for Symbian devices has been updated to a new version, and the update can be installed by opening the store application on devices. On firing up the Nokia store on the devices you will be prompted with the update information.
This is a bug fixing kind of update and brings purchase related and download queue bug fixes to the Nokia store.
Nokia Store on my N8 is already on this version, downloaded from Nokia BetaLabs. Seems now it is rolling OTA for all of the Symbian device owners.
