Would the Gophone SIM Card work for the iphone 3G?

If i went into the ATT store and told them I was already a customer, could i just plug in a GOPHONE sim and be done with it?

Ya sure the AT&T go phone sim will work freely in iphone 3g only if it is unlocked one else if the iphone 3g is locked to some other network provider then it wont accept AT&T sim until you unlock it .You can easily unlock the iphone 3g from network lock using sites like ClassicUnlocking.com here they are rendering remote unlocking service to unlock all model iphone from network lock .You first check that whether the service is available for your country and network provider .If yes then pay for it and unlock your iphone 3g then freely use it with any GSM sim ...
