If you load a PWN'ed firmware on the 2G that is "hacktivated" then it will work fine with just placing your current 3G sim in there.
Yes, and that sucks.
You either gotta activate it thru itunes and go thru picking a plan and signing a contract or just unlock and jailbreak it.
Then it will work with any sim.
The 2G sim will work inside a 3G iphone but not the other way around.

Does the 2G sim in the 3G phone get 3G service?
I have a 2G right now and am getting the 3Gs with intentions of using the 2G as backup or if i'm going somewhere I dont want to risk damaging/losing the 3Gs. Hmm...
I switched it and plugged it in to I tunes and activated it. I called Att to make sure it will work like this and they were confused as hell. So... i switched them back. Im worried that it will mess up my 3GS order since I ordered it under her number to get the discount.
Ok i just pulled out the sim card on my 2G phone and it has the 3G logo on it. So i should be able to switch from 2G to 3G whenever I want with the same sim card? right?
Why don't you just get a new SIM? There is nothing mystical about your old one.
Bad analogy. There's no technical limitation of the SIMs , it just has to do with the activating of the phone.Not too knowledgable in this area but I guess it'd be like saying why won't a PS3 game work in a PS2...
Bad analogy?
It is suppose to work. I would talk to ATT you have need and updated SIM card. I as well was hoping to use my 2G as a backup when I get a 3GS
So use it as a backup. If something happens to your 3GS drop a new SIM in your 2G and have ATT activate it. That will do nothing to your contract.
It seems to me like the original iPhone did not come with a 3G sim if you bought it in the first summer that it was available. However sim cards after a certain point are all 3g capable. So as long as you have the new updated "3g" sim card it will worth on both phones?
If you put in the 2G $20 data plan and using the sim on a 3G they'll eventually find out and tell you to get the $30 3G data plan.
You should be good if you'll only do it for a week IMO.
People have been doing it for a while and usually get caught after months.
But it doesnt really matter if you turn 3G off in the settings, AT&T knows right away what phone you're using as soon as you stick in your sim card to the cellphone and connect to their network.
