3GS iPhone SIM card in 2G iPhone

[Renkman]

I have a iPhone 3GS. I am selling it tomorrow. I also have a 2G iPhone. The SIM cards are identical. I swapped the SIM cards so that I can use 2G iPhone until next generation iPhone comes out this summer. However, iTunes wants me to activate 2G iPhone as if it were new. Will this work? Will I be charged by AT&T? I thought swapping the SIM cards would work flawlessly.

Please help?

Go ahead with iTunes activation?

I use to use 2G iPhone without a data plan on AT&T and then got a 3G iPhone and switched the sim card and used the 3G iPhone with no data plan on AT&T. So I am pretty sure you will be fine. I don't think activating the phone is all it is made up to be. It seems like it just checks for an AT&T sim card and thats it because if it did anything else I would of found out.

So YES, just activate your phone.

So YES, just activate your phone.

Worked Great, thank you! Plus now with the 2G, my data plan is $10 cheaper for a month.
