My wife's iphone (original) started skipping and pausing when using her new apple earphone with mic. She thought it might be something to do with the fact it was the 3GS earphone and mic, so then she went and bought the one just for the first gen iPhone. But, the same problem happened. I have tested both her earbuds and they do the same thing to my iPhone 3GS. She has tested all earphone combinations with her old nano and no problems. This is very weird, just seeing if anyone else has had these problems.
