No, AOSS establishes a wireless connection.
The DSi itself doesn't have an AOSS button, it's something on specific routers. You'd press that button, and the DSi will briefly communicate with it in AOSS mode, which will let the DS automatically set up its wireless internet.
Yes of course!
Yes they do. It's about 100$.
