This tuesday, I'm moving to Urbana, Illinois to study for one year. I probably should have many questions for you, but right now I can only think of one:

I have a cell phone which I know works in the US. I need to buy a SIM card for it as soon as possible though. How/where can I do that? Pre-paid SIM cards like we have in Sweden would be nice, to get rid of bills -- is it possible?

It would be really nice if I had a working cell phone asap, because I going to meet up with a friend to buy his car etc.

EDIT: Is there anyone here who is/has been to UIUC?
