    So I'm going to be switching from an iPhone 3GS to a 4s on at@t. I was wondering if it will come with the micro sim in the phone or if I will née to go down to AT&T to get one. If I do need to go to at&t can I go before friday?

    When I upgraded from my 3GS to a 4, it came with the Sim. You will have to turn off your 3GS (not sleep mode, total power off) before you turn on your 4s, and the 4s should activate OTA.

    I bought it from apple. Will that make a difference?

    Nope, just turn off your old phone then power up the 4S when it comes in the mail and you'll be good to go.

    It activates when it connects with the cell towers.

    A micro sim is pre-installed. As soon as you activate your 4S AT&T will deacticate the sim in the 3GS.
