SIM Card to new 3Gs?

[Trimmer2]

So, will we be using the Sim card we currently have in our 3G and put it in the new 3Gs?

I believe you just get your account/number transferred to the new SIM.

You will get a new sim card with the new phone, but there isn't any reason why you can't take your old sim card from the 3G and put it into the 3GS.

You can use the old one or the new one, all the sim cards are the same throughout AT&T. My sim card stopped working for some reason on my 2G iPhone and AT&T just gave me a new one to take home and put into it... they aren't specific for the iPhone.
