I saw some people saying that ipod touch 4g has louder speaker, and some people, the other hand, say 4g isn't loud at all Has anyone compared 3G (not 2G) with 4G? Despite people think 2g and 3g have same speaker, I think 3g is way louder than 2g. Because when I compare my 3G ipod and 4G ipod, 4G ipod is way more clearer but, much more quiet too. Can someone who has both 4g and 3g test this ? I just wanna know whether mine is defected or not.
