Can i put a straight talk sim card in an iphone 4?

You can buy a Straight Talk sim card from the Straight Talk website for $15 and use it in a Iphone. You can't take a sim card from a Straight Talk phone that is already activated. Once a Straight Talk sim card is activated with a Straight Talk phone, it is locked to the phone and can't be used with another phone.
