ok, so i am looking for a speaker grip for my DSL, and was wondering what my options are. it would be preferable if it allows me to attatch it to the power port of the DSL, so i am able to get a little extra time out of my DS when i go bush with mates. does such a thing exist? or is it onyl possible to get a grip that attaches to the headphone socket? if what i am looking for isnt possible, is there any links for DIY hardware hacks i can knock up to allow me to do what i am asking?
