Heres the situation

My wife has a 3G. I have a 3GS. I want to give her the 3GS and buy a 4G. But for contract reasons (mine is on a corporate contract) I will end up upgrading her 3G to a 4G and then swapping my 3GS for her new 4G.

Follow so far?

Last time I did this, I just swapped the sims. but how do i do that if the sims are different sizes? Any thoughts?

How are the SIM cards different sizes AT&T uses a micro sim adapter for the iPhone 3GS like they do the iPad? I understand that when it comes to the iPhone 4th Generation it will be running the same iPhone SIM card in the past...

Go into ATT store and explain to them what you want to do when you get the phone. They should be able to give you a micro sim.
