I have a question for you guys... After the 4.1 update, my iPhone receiver (ear speaker) stopped working... I tried restoring 3 times (even in DFU mode!) and nothing. So I'm going tomorrow morning to the Apple Store, appointment booked and all. The question is: my iPhone has the invisibleshield. Should I leave it on? Remove it? If they need to give me a new phone, will that be a problem if I leave it on? Does anyone know?
