I've posted a full tutorial & roundup of all these to http://www.iphonelife.com/blog/87/h...-gear-keyboard-mouse-gps-game-controllers-etc , including high-quality(!) demo videos and a lot of goodies.
Sorry, I can't really cross-post it here because it's HUGE and has a lot of inline images / videos, which are a pain in the back to convert to the vBulletin format.
