How do I change the delay between rings? I have an HTC EVO Shift running Android 2.2 (Froyo). When I receive an incoming call the ringtone plays constantly. Each cycle starts immediately after the previous cycle finishes with no delay at all. This happens regardless of which ringtone I select. Short of editing the audio files, is there any way to set the delay between subsequent ringtone cycles?
Bryan above is correct.  There's no way to add a delay, at least not without a custom ROM.  To introduce a pause between the rings find an MP3 you like and use something like Audacity to append a few seconds of silence after it.  Then use that file as your ring tone.
