I want to change the alert sounds for various events: email notification, SMS, power status, Google Talk, etc. I can change the alert sound via Settings->Sound & display->Notification ringtone, but the sound is identical for all the various notifications which seems ridiculous. Is there an app or widget which allows me to assign different notification sounds to different events? Thanks. I downloaded an app called "Sound Manager" but that only allowed me to adjust the volume on various event notifications.
