Call quality on the iPhone is pathetic, and it's mostly because of the tiny speaker. It has to be aligned with your ear or else the volume cuts down to nothing as the sound waves bounce uselessly around your ear shells.It drops calls, fails to connect and doesn't even ring sometimes - not for everyone, but more often than any other phone we're currently using.But this could be also due to the connectivity problem. I have heard me friends using other phones having the same complain with At&T. So that doesnt stick to iphone alone.So with no ring or vibrate to clue you in, your friends and family...
