bro... the speaker of iphone 3g is slightly improved than the 2g speaker... as far as my concern, if u really neead a loud and powerful speaker... iphone is not for u man....
for quality wise... the update of 2.2 Firmware improved the sound quality when talking on the phone... but its not as loud as the nokia, sony ericsson, samsung or LG. always got scold by my friends as sometimes i cant hear their call despite i already put my vibrate on.....

so my solution is using an earphone since i always listen to music....
but hey.... if u really wanted loud sounds and all... iphone 3g is not for u...

this is my personal opinion...
