I ordered an AT&T 6820 from Nokia. I tried using all the 6800 codes generated for my phone, and none of them worked. I either recieved a "Code Error" message, or "Cannot change restriction".

[.:illusion:.]

cannot change restriction means you have attempted to enter the code 5 times unsucessfully and code unlocking will no longer work. the only solution you have is to get it unlocked by a cable.
