I used iTunes to convert all my .mp3s and they sound ok on the DSi. Collecting coins is fun to do when you listen to your music.

I don't think you understand what I mean. When I get to school early, I will sometimes play Mario Kart or COD4 with my friends (theres like 12 that haves the ds :D). The iPhone cannot do this and even if it could I would have no one to play with. And actually my dad has an iPhone that I use often.
