there is a feature in new generation if hyper card which you can manually enter the ICCID.
people with officially activated 1.1.3 or other firmware may try to enter their ICCID from the official sim then paste the card to other sim cards.
and this might works, also good for people to roaming around quite often.
since i don't have a officially activated iphone so i can't try.
any one can try this?
