again i know you all are having issues with volume level of the earpiece, however i have had 2 iPhones already. when in the middle of a call, turn the volume up on the side of the phone as high as it goes... i swear to you on my life you must not have the phone up as high as it goes... i promise i am not calling you all retarded, i know thats a normal thing to do is reach for the volume in mid call when its too low, but i work as a club promoter and went from my motorola v3i to the iPhone and my iPhone is by far louder in earpiece volume (both of them, i bought the first one on a thursday, was at the clubs thurs fri sat night and then returned it monday and was at the club wed night and was able to hear while upstairs in my skybox right next to the dj booth)
i hate to say it, but maybe its a hardware thing among phones purchased at different times (see the thread about different screen types from initial release iPhones to current release iPhones)
maybe they changed the earpiece? either way i am completely satisfied with the volume level and i will do some looking to see if i can find volume controls within the iPhone, and let you all know if i find anything of note.
