LG MM-535

I've had the phone about a week and am wonder if anyone else has had the sound quality of some of their ringers degrade? I suspect it may be because I have more ringers (qcp) than they anticipated the average user to have. I think I put about 92-ish on the phone because it won't let me put any more even though I have 15 MB of space left. which is aggrevating. I'm trying to find out if any other phone with a good amount of space (16 MB+) has no limit on ringers. of course, i have 7 days to do so if i want to cash in on the return policy for the phone. so quick replies would be appreciated.
