My jack is not working.

Sup, so I've got an 4s and I noticed that my jacks water sensor is pink and my headphones are not working.

I've done a restore of the ios 6.0.1 and still not working.

The thing is my phone never touched the water and I don't understand how this happened.

I tried about 4 different pairs of headphones and no result.

I'm posting here with the hope that someone had the same problem and fixed it somehow.

Not by changing the phone , cuz I don't wanna give them money for they're faults.

So please help me out.I'm a music junkie.

Everything works on this phone except the jack. Volume control buttons , silencer button working great.
