Hi, for some reason this morning none of my headphones will fit into the headphone jack of my 4S. I tried two earbuds and a SONY headset but none of them worked. The headphones DO work on my computer with no issue. They fit in, but only up to the point where the last metal segment of the headphone is still sticking out of the jack. I have tried to push them in but for some reason it won't budge. I'm really confused as to what is going on, I haven't had any kinds of problems like this in the 2 months I've had the phone. I called Apple and apparently the only thing they are willing to do is replace the phone. I'd rather not have to go through reloading all of my stuff into a new phone and it works fine, the only problem is with the headphone jack. Anyone know what the problem is or any way that I can mend it without having to resort to a replacement. I do have warranty but the nearest Apple store to me is like a 3 hour drive. As a last resort I'm thinking about just getting a set of blue tooth headphones, that would work right?
