I have an HTC EVO 4G for my daughter. I wud ike to be able to block the wifi on the phone so that i may enable it when i wish. I downloaded an app lock and i am able to block apps and settings etc. However, i noticed that once i locked the apps and the settings app - i am still able to long press on the home screen and add a wifi widget to turn on the wifi. How can i stop this? I wud like to grant her access sometimes but not anytime she wishes.
