I know this thread is going nowhere quick but I was involved in the beginning and wanted to follow up as I was away for the weekend.
You can’t disable the ipod restrictions if they are properly set unless they reset the ipod, or they figure out your passcode. If you have proof otherwise, I would love to see it, but I’m confident it doesn’t exist. If you know what you’re doing locking it down, internet will absolutely be restricted as much as you want it to be.
Would I know if my child reset the ipod? Absolutely I would, but I realize not everyone is as technologically inclined. And if you wanted to take it one step further, have your ipod sync to an itunes on a computer username that only you have the password to, so if they tried to sneak on the computer and reloaded all the programs back on to a fresh install, they wouldn’t be able to.
