Help with my Iphone 4

Hello people how are you? I hope everything going fine and well.

OK the problem started today.

I am Iphone4 running 5.0.1 jailbroken already.

It was working perfectly fine, then I have installled a tweek for the notification bar called " Omnistate"

then if someone call me I cannot hear it from the normal headphone, I have to put it on Speaker to listen to the caller? BUT they listen me 100% good

so what do you think has happened?

I have restored it 3 times now and still not working

Please help me.

thanks guys

I have solved it by " Resetting all the setting " thanks guys
