I also would like to know know why it would be necessary to remove the board before removing the speakers? Nothing is prohibiting the speakers from being removed right away.

Help!! - I replaced the battery without issue. Battery came out easily and new one put in. Everything works but there is no sound or mic when making a call. Seems to freeze when ending the call as well... Everything was working before... frustrating as nothing was touched anywhere else on the phone... anyone else?
