If you are familiar with FlipSilent for your Nokia N8 then Turning Control for you won’t be such a new thing. Turning Control is a default feature that can be accessed by going to Menu – Settings - Phone - Sensor Settings - Turning Control. The function of this feature is that when someone calls you, if the feature is enabled, you just turn the device upside down and the call goes into silent mode, the call eventually goes into voicemail if you have it activated.
If you prefer FlipSilent then click here to download it then transfer it to your device. This app hasn’t be tested with my Nokia N8 therefore I cannot say if it is worth it to download it.
