After the OTA update this app couldn't find the file in the phone to read the unlock codes from, thought the AT&T update took the file out just to prevent the unlock, but the file with the codes is still there just with different permissions. Rooted my captivate, found the file "nv_data.bin" with Root Explorer, changed permissions to "read, write and execute" to others, ran the app again and voil?! got my unlock codes in 3 seconds, happy man again....just in case this might help someone outhere.
