I just bring my iPod. One time during math class,I was so bored cuz what we were learning,I already learned in Challenge Math,so I just pulled out my iPod and listened to a whole MCR CD and got away with it!!!!! I actually broke me GameBoy cuz,well,I can't remember. But that top,flippy-part,I snapped it off the rest. lol and I don't have a cell,or a DS.
