The update includes new icons, a portrait on-screen qwerty keyboard, and a new web browser. The Ovi Maps application as also been updated, and several enterprise features have been added such as hardware accelerated encryption and several other additions related to security and messaging. Also: homescreen navigation is now real-time.
Nokia also announced two new Symbian phones today. First, the Nokia E6, which has a 326ppi display on a qwerty portrait phone. This device is squarely aimed at business users, and I can assure you, at least here in Europe these things are still incredibly popular. I had a E71 myself, and even in the days of the iPhone and Android, it was still quite pleasurable to use.
The second one is the Nokia X7, a 4" touchscreen phone, which looks incredibly beautiful.
So, despite going Windows Phone, Nokia is still getting some Symbian updates out the door, which is good news for owners of the N8, E7, C7 and C6-01, who will be getting this first update over the coming months.
