During and after tethering, I am unable to make outgoing calls. The problem persists until I reboot the device.
Does anyone know about any fixes for this, or what could be the problem?
iPhone 4, iOS 5.1.1

Q: I have an annoying issue with tethering.
Are you on ATT or Verizon?
I believe if you are on verizon, you cannot use phone and internet at the same time.
It is because of the nature of the verizon cellular system.
