Sorry if this has already been answered but I could not find a specific answer. I am looking to see if I can somehow lock my sons iPhone (3GS) to keep him from being able to turn off WiFi? I do not want to totally lock all of his settings, etc, but do want to insure that his phone uses WiFi whenever there is a usable connection (cell data is fine if the WiFi signal is not there or he is unable to join the network for whatever reason). Thanks, B
