4s Question

[bluespider]

I bought a 4S using my son's upgrade, when it comes, I want to take the sim out of my 4 and swap it so that my son has the 4 and I have the 4S. Will this work or do I need to do something more?

from what i know the sim hasn't changed so the micro sim you currently have in your 4 you just put it in the 4s and it will work straight away and you won't need to do anything.
