all very well it is possible to boot into ubuntu and the likes however that would require downloading and making a bootable device.. thus requiring being online first, if they have access to the internet they can install apps simply by going to play. google. com and signing in you can than remotely install apps or if they just download the apk’s.

hacking an iphone until ios 7 at least consists of plugging it into your pc going to the relevant website, paying the small fee and clicking the jailbreak button…
once on ios7 i believe there are some new parental control restrictions (i havent seen or tested that out yet)
basically back to the point if you dont trust your kids you gotta problem
