To those of you with iOS 5.1.1, do me a favor and go to Settings/Phone and see whether or not the call forwarding, call waiting and Show my phone number features are present. Mine are no longer present and I don't know whether or not it has been that way since I updated to 5.1.1 or whether my device needs to be reset as new. Any assistance is appreciated. I've attached a screenshot of what my phone settings look like, by the way.
