Posted by Symbian users who are fans of Windows Phone 7’s Metro UI can have some feel of it on the new range of Symbian smartphones – Nokia N8, C7, and E7 inclusive.
All you have to do is install the Symbian Phone 7 theme. There are no live tiles, but all standard icons are replaced with blue squares.
Go ahead: give it a go. Download Symbian Phone 7
Looking at the screen shots, the theme looks nice, and I particularly like the blue and orange combo.
