Answer to: How can I repair my iPhone 4 earpiece speaker?Yes. Basically the earpiece is not broken. Only the connection to the logic board is week. So what you need to do is follow the guide on disassembling the logic board and reach the earpiece. Once you are there try to bent the left contact a little upwards and to the right (my problem was related with the left one). You can look on the bottom side of your logic board to see which contact of the earpiece doesn't touch the board by looking at the small scratches on the contacts of the main board.
