I know how to turn the volume up for the ringtones through sound preferences, but some of these things are really low, even at "full volume". I've downloaded some other ring tones and can barely hear them. The only one that I can really hear while I'm in the car, or walking around, is the one that sounds like an old phone ring. (no, I don't have hearing problems). Anyone else experience this? Is my 600 screwed up or is there something I'm doing wrong?

Thanks
