Ok so my ear piece or whatever just stopped working. I had scheduled a genius bar appointment earlier and I was cleaning my iPhone the night before when part of the glass around the ear piece cracked. I know it is my fault that the glass is broken but I cannot go until February, which is the next time I'll be able to get a new phone, answering all my calls on speaker phone. Do you guys have any advice on a good approach to handling the Genius Bar?
