We all use .wav files as ringtones. just email it to yourself. Try to open it and that opens "Manage Sounds" and you will see it in the sounds list as "???". Rename it (or not), then go to Preferences/sounds and alerts and choose it as a ringtone. Done, no news flash. I just did it with 3 more, 15k, 16k and 878k, no problem. A 4th one (15k) will not play when selected. It will not play when the phone is called (silence). I delete it and go back to the pc and it plays there. I send it again, same result. I delete it, go back to the pc, rename it and it plays. Email that version, same result. So theres nothing wrong with the file or getting it to sounds and alerts. Anybody know why it fails?
