Symbian Guru Rcadden has got his hands on the latest version (v12) firmware for the N95.
Key features in this upgrade are not clear yet ...but one major upgrade is in the form of a new nokia maps application and a much faster GPS lock on (due to Nokia using A-GPS technology by storing your nearest cell-id's in their centralized servers for a faster lock ).
I also hope nokia has optimized the ram and improved the response time of the camera. Also a bit of optimization on battery life wouldnt hurt either.. :)
To read more about the new firmware head on to..
UPDATE : V12 IS OFFICIALLY OUT. CHECK YOUR NOKIA SOFTWARE UPDATER !!
