He's blowin smoke. On skyrocket the unlock code is stored in EFS partition (not the /efs mount point, but mmcblk0p18 and 19 partitions) and these partitions are encrypted. Only the radio code can read it via a decodeEfs() call. It's is not as simple as reading a raw hex value or it would have been done long ago.
Most likely its not even the unlock code that is stored there but rather an md5 hash of the code plus the imei to compare when the 8 digit code is entered by the user.
I don't know, I mean it was in plain text on m Galaxy Mini.
You may be right though, I have not tried to unlock my T989 yet. Almost the same phone.

It may be easy to simply over right the hash with the hash of a known string. example 000000000000 or something like that then type that in to unlock it.
It honestly cant be all that hard.
They even sell boxes in China for under 300 dollars that do this and even program "repair" IMEI codes on all Samsung devices.

dont think so, Lock codes are IMEI specific and unique to each phone.
They are IMEI specific among other things, but how does your phone know you got the right code? It is checked against the phones internal memory.
