does the s3 have an sd card?
i thot it wsa like the nexus with an internal,nonremovable sd. but,its samsung... so i could be wrong
if it has an sd card spot,i see no reason why you couldnt use it to make the gold card. you just need adb to read the sd card CID. youll need to figure out wetehr the s3 mounts the sd card at mmc,or mmc2.
try the gold helper app,and see if it will run and give you the inverted cid
