I have parental controls setup on my son's iPod and installing apps requires my consent. However, he's now been shown by a friend how to install Tweakbox by installing a profile (doesn't require parental consent). That in turn bypasses the iOS controls and gives him access to install anything from the tweakbox store without needing my consent. I've tried to find online info about whether tweakbox represents a security weakness (over and above normal jailbreak issues) and whether it is 'safe' but can't find anything. Equally can't find any info on how to block Tweakbox on my son's iPod. Any observations / suggestions re Tweakbox?
