Question on Setting up iPhone 4S

[Wicked1]

Ok, so I never did this before as I have always picked up my new phone from Apple, but have a question when I get my new 4S tomorrow from Apple.

Do I use the SIM card from my iPhone 4? or do I keep the new SIM card in the new 4S and Activate thru iTunes, or do I have to call AT&T?

I figured it is as simple as using my 4 SIM card, but not sure if there are changes in the 4S SIM cards, does anyone know for sure???

Once you activate the phone by plugging it into iTunes it will disable your old sim card and you will be good to go on the new 4S. No need to swap any sims around.
