Nokia has just sent out invitations to a special event where they will talk about what’s new with their Symbian smartphones. Scheduled for 10:00 CET in London, the event will happen next week on April 12. The invitation is devoid of any details, but judging from the graphic, it’s going to be about Symbian smartphones. Perhaps they’ll be talking about the last major update to the OS before it fades away and is replaced by Windows Phone 7? Or maybe they’re going to announce that Symbian is here to stay? We won’t know until next week, so stick around and we’ll keep you posted. Any predictions on what Nokia will reveal?
