I did a search on this and found one thread with a similar complaint, but I didn't see enough responses to satisfy my OCD. So, I just got an iPhone 3GS (love it!)... my only complaint is the distortion of the speaker at high volume. When I use iPod feature and put the volume at max volume, the speaker sounds slightly distorted. Also, with most YouTube videos, the volume doesn't even have to be near max to sound severely distorted. Does anyone else experience this, or might I have a defective unit? It sounds fine with the volume lowered.
