Question: If you have an iPhone 4, can you just replace the microsim in the 4S with the microsim from the 4? I am giving the phone I used my upgrade for, to my wife. She has an iPhone 4 already.
I did this and it works fine.

Seems those of us on AT&T who ordered from Apple are stuck needing to
a) Get a "cold SIM" from an AT&T store to activate the 4S on the line it was ordered on. I'm going to assume doing it this way will deactivate the SIM that the line is currently using. Which is no good for those of us swapping with people in other states/countries.
b) The pittmann87 method in post 94 - if AT&T has already swapped the ICCID and IMEI of the 4S to the line you want to use it on (different than what it was ordered on) you need to insert a microSIM that matches the number the 4S was ordered under from Apple to activate the 4S, and can then switch around. Only works for those switching between 4 and 4S - microSIM phones.
I don't believe that any amount of waiting for Apple & AT&T's servers to sync will fix this issue - sounds like phones ordered from Apple are tied to only activating on the line they were ordered on.
For me, I'm stuck as I want to swap with someone currently using a 3GS that lives several states away and is currently traveling and needs a phone. I'll have to wait until next week to convince him to be without a phone for a day and then I can do a 'cold SIM' swap and overnight my 4 to him.
Beyond frustrated that Apple and AT&T could not get their ducks in a row and get this process communicated and documented better. It shouldn't be this hard.
Regardless of what AT&T or Apple support says, you *have* to insert the SIM of the phone with the phone number that you used to order the upgrade from Apple.
Insert the SIM from that phone into the new iPhone 4S, do the activation, then swap back whatever AT&T SIM you want into the 4S.
After you activate, you have have AT&T move that phone to any phone number on your family plan, etc.

My Upgrade Swap - ip4 to 4s
I did not call AT&T.
I first waited till 5 AM Sat for the insane traffic on the Activation Servers to die down.
Backed-up and Restored old ip4 to factory settings then powerd it off.
Activated new 4S on upgrade line per ATT instructions w/ sim that was shipped with unit then powered it off.
Swapped Sims
Turned on the 4s & restored from backup
Turned on ip4.
Everything WORKED.
I then checked my ATT account online for device & phone number associations and it automatically picked up the swap with the appropriate device now showing up on the associated phone #.
Mission complete.
I had to go back to the AT&T store for a second time. I asked for a micro SIM with the original number. We tried that and it didn't work the first time but we waited a few minutes and attempted again and it activated. After that we just had to get a new SIM for the original line, remove the iPhone data plan, and put the sim for the number I wanted swapped to back in the iPhone.
