Unlocked Samsung Galaxy S / Captivate

Someone found a way to unlock these things. In summary:

1. Root the phone.
2. Get Terminal Emulator from the Market, or use "adb shell" if you have the Android SDK.
3. Type: busybox grep -E ^[0-9]\{8\}$ /efs/nv_data.bin
   
   On mine, I get something like:

   12345678
   12345678
   00000000
   00000000
   00000000
   00000000
   

   It's 8 digits. Repeated 2x. It's not 00000000. As you can see, it's pretty obvious on my phone.
4. Pop in your "foreign" sim, and enter the code when prompted.
5. Bye AT&T...
