Only a minor update, but noteworthy because the app's so central to Nokia's new Symbian^3 handsets, but check Sw_update on your N8. You should see a 2.5MB update to 'Social' and it will install over the air. Do note that a phone restart will be needed as well, presumably to add a newer version of the Nokia Social widget to the homescreen system. Comments welcome if you notice any actual changes!
