Nokia has released “Nokia Maps” data update for Symbian devices. It is available for both 808 PureView and N8, so seems that all other Symbian devices also be getting the update. The Map version release date is 17 December, so it is really up to date version.
You can go to “Map Loader” on your device after opening Nokia Maps and check for the update. Good to see continued support for Symbian devices.
