SIM swapping between a 3GS and a locked and unlocked iPhone 4
I would like to purchase an iPhone 4 in Canada where I understand they are or can be purchased unlocked.
The goal is that the user of the locked iPhone 4 will replace it with the unlocked iPhone 4 and the user of the 3GS will replace it with the existing locked iPhone 4.
The reason I want an unlocked phone is so I can purchase inexpensive SIMs to use while visiting Europe. I know this is possible because a Canadian friend whom I was with in Amsterdam did it.
My thinking is that all I need to do is buy the new phone in Canada and then move the SIM card from the old iPhone 4 to the new one and then move the SIM card from the 3GS to the old iPhone 4.
Will this work? Or do I need to visit my local AT&T store and have them move our accounts around on the phones?
Thank you.
