    Hi,

    In order to get an iPhone 3GS at upgrade-eligible pricing, I upgraded a line on my account which is not currently an iPhone line. Currently I have an iPhone 3G. When the new 3GS that I ordered comes, can I just pop in my current SIM card into the 3GS? Then, can I use my iPhone 3G to the line that I ordered the 3GS for? Will this all work seamlessly?


    Thanks!

    I could be wrong, but I think what you will want to do is activate the SIM in the 3GS first, then just swap SIMs.

    So you're saying that I can't swap in my current SIM card immediately when I get the phone?

    I would call AT&T and have them walk you through it, just to make sure you're doing everything correctly.

    That's what I did going from v1 iPhone to 3G, but I think this time around going from 3G to 3GS they just left my old SIM card out of the equation. As others have said, give AT&T a call and they remedy the situation....:cool::cool::cool:
