Alright, I have installed the Show Hidden Phone Settings.cab from
this post and now call Call Forwarding shows up but I get a "Network Error" "Cannot read settings from the network. Try viewing settings later, or disconnect data connection and try again." All of the other options work except this one. I do not have any data configured with AT&T and all of the settings are the Verizon ones. Do you think this could be the issue? Does anyone have call forwarding working on AT&T with a Verizon TP2?
