Today i have been playing around with my Nokia N95, i recently found out (i know its took time) that it has a built in Accelerometer which means you can do some pretty cool stuff with it. Ive just managed to install FlipSilent which is a pretty good app. Basically say you are busy and your phone starts to ring, rather than cancelling the call all you have to do is flip your phone over and it will automatically change to “Silent Profile” or if you go into the settings menu you can change it so it automatically cancells the call when you turn the phone over.
To get this to work you can download the app from HERE but at the moment there is only an “unsigned version” which means before you can install it you will have to get the application “Signed” to run on your N95.
This took some time, but after following the instructions which can be found HERE it will work no trouble 
Hope this has been helpful! If you get stuck then please get in touch and i will be able to get it done for you!
