If you own an HTC Desire running a rooted Android 2.3.5, you may have experienced issues with clearing or cancelling a missed call notification when using a third party dialer app, like XDA forum member manny73.
Because of the issues, the XDA forum member has developed a simple app that is configurable for checking missed call notifications and lunching a customisable notification with a reminder which returns to the default dialer. In order for this to work, the app must be installed under /system/app and your phone rebooted after install. The app was only tested on the HTC Desire running Android 2.3+ (rooted).
