What happens during iPhone activation?

AT&T/iPhone: I bought an iPhone 4 on craigslist. I plan to cut down my 3G's sim into a micro-sim and put it in the 4. However, before I got started I factory reset the 4 and now it wants to go through an activation process. What does "activation" mean, in this context?

I have an old "unlimited" data plan from AT&T and would like to keep it. Does the activation process trigger anything on AT&T's side, or is it simply reading the data from the sim?
