Nokia 701 supports multitouch but it is not used in any part of Belle O.S.
I have seen N9 demo, in that a guy rotates the maps using two fingers and the map rotates accordingly.
Multitouch is used in games like Asphalt HD.
I'm posting this after using particles qt game from Nokia store(free). It supports multitouch, maybe upto 10 fingers or more.
I request Nokia to apply this feature in Nokia maps. It would be awesome if we are able to rotate the maps.
It would be even better if this multitouch is applied for moving widgets and shortcuts in the homescreen too.
I hope to see this happen.
