can I take the sim card out of my new 3g and put it in the original iphone and it work correctly? just like swapping out sim cards on reg phones
 
I was able to

I plan on using my old iPhone for foreign travel, so I jailbroke it and unlocked it (Thanks, iPhone Dev Team). My old sim does not work since the number has been transfered to the new phone. Before unlocking, it said something about invalid sim, but after unlocking, it worked and I was able to place a call.
 
do you reckon it will be okay if i put my new 02 sim card from my 3g into the old iphone which i had unlocked and accidently upgraded to 2.0 a while back and continously got the emergency calls only screen invalid sim etc?
