Instead of having the hard to see little phone icon on the top right of your Blackberry Home screen that notifies you missed a call, in OS 4.0 you can get a window popup instead. With the window popup you can easily view the number that just called you, instead of trying to find it in your message list.
To setup popup notification, do the following:
1. Click on the Phone icon.
2. Wheel-click and go to Options.
3. Select General Settings and make sure ‘Phone List View’ is set to ‘Call Log’.
* Note, in some OS versions, you will need to go back to the Options screen and configure ‘Call Log’ for Missed Calls or All Calls.
