well as u all know i just bought a D600 off of ebay because i live in the U.S. and have a contract with cingular but cingular doesnt carry this phone. The phone was already unlocked off of ebay but the internet and the multimedia messages wouldnt work so i did some searching and found this code to unlock the D500 and tried it on my D600 and it worked.
