How to set the default dialer? Where are the configurations to set the default dialer? I installed a new one and want to know where I set the default.
Go to your Settings -> Applications -> Manage Applications. 

Select the 'All' tab and scroll to the current dialer app. 

Scroll down and press the 'Clear defaults' button. Now when you select dial, you should be prompted to select a particular app and also have the opportunity to set a new default.
