Although the word out is of the Symbian version 3 (S^3) but today Symbian Foundation has posted some videos at the first glimpse of what we can expect from Symbian^4, which is due to release in 2011.
By the looks of it, I thought it was cross between all the Android, iPhone and remaining OS already available in the market with multiple screens and drag n drop widgets. Also the applications screen is shown along with picture gallery. There was not much revealed in the videos (below) but we can expect Symbian to built in a lot more till the time it is available in the market. Waiting for more to show 🙂
