I was just looking around on whether is there a simple or easy way to unlock Samsung Galaxy S3 and you know what I found a very simple way to accomplish this. This is yet to be confirmed by myself to work on AT&T Galaxy S3 and it is reported to work on ALL VARIANTS of GSM.

Please do not profit off this…..as this is completely free.
