For some reason, my location services option cannot be turned off. It is greyed out and locked in the ON position, making it impossible for me to change its status. I am using OS 3.1 and never have WiFi enabled, don't use it. I have reset the iPhone with no change in the situation. Can someone tell me the cause of this: Thanks and regards, ralphdn A brief PS if this is allowed: Is it possible or recommendable to downgrade to the previous OS version when problems like this occur? I do not believe that this is an OS 3.1 problem, since I updated some time ago and I believe that this problem only began recently.
