Right this is a little bit of an odd one. A young family member has been issued with an iPad to aid with his education (He has some learning difficulties and its helping loads apparently). Now i have to confess ive never ever used an iPad so i have no idea about the way they work, but im assuming it similar to the iPhone? What we are looking for is an App that uses simple math sums to unlock the device. Basically: To unlock and use the device 3/4 sums must be solved, nothing hardcore hes only 11, so simple arithmetic etc.. I have had a look but cant seem to find anything useful, my google-fu is weak today So does anything like this exist?
