I appear to be having the same problem. I never had any speaker issues but when I press around the vibrate switch it jumps back and forth between vibrate and sound mode and is rather annoying. First problem I've had with any iPhone so far and if it keeps up I might go to the Apple Store this weekend. I tried restarting, haven't restored, but somehow I don't think it is a software issue.
