When Incorrect SIM (I got invalid card and there was a sim card graphic spinning) error comes up, type *#9998*3323#.
White screen will appear with an exit option. Press the right softkey. (I ended up pushing the down key to get a menu)
From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
Turn off your phone and put the original SIM back in.
Turn on your phone. You will receive a prompt to enter a password. . Type 8 zeros (00000000) (This is because the SIM LOCK Mentioned earlier gets switched back on)
. Completed. You have now unlocked your phone.

Easy as pie. Now you have an UNLOCKED Samsung D807 =) worked on my brand new 2 day old Samsung D807 phone.
