Try restoring phone. If that doesnt work,bring the phone into Apple Genius Bar.

Jailbreak will not help with signal.

No, Because ultrasn0w isnt compatible with 4S basebands.

I think you should just take it into Apple Genius bar, phone is still under warranty since it was just released like 4 months ago.
