For those of you who own a locked Vibrant or Captivate, you can now unlock your Android device yourself, for free.
XDA forum member galaxysguy has posted the instructions on how to unlock your device in the forums. You’ll need some knowledge of adb, and will need to open the bml3.bak file in an hex editor. The unlock code can be found in the file.
The method was originally discovered by XDA member rhcp0112345, who is credited in the thread.
There are mixed reports so far on different versions of the Vibrant and Captivate, but to try it out for yourself, check out the modification thread._________
