I just Unlocked my Samsung Galaxy S Captivate (sgh -i897) locked to att and put my tmobile card in it. I did however pay 19.99 through paypal though, but it was well worth it, I used this site ----> I had the full link here but cause i am a new it wouldnt let me post it, go to fastgsm dot com ,watch the video, download the drivers (swallowtail- shrewsbury driver) let them install, then download there program and hook up the phone with the usb. Mine failed first time, but i didnt let the drives finish loading like the video says. second time it gave me the unfreezed code and unlock code

100% real guys I already wasted 20 bucks on other sites just for them to tell me there issueing a refund cause they cant generate a code. good luck guys!!!!!
