unlocking a nokia 6030 - tmobile to att?

[LordSnailz]

does anyone have any experience with unlocking a nokia 6030 from tmobile to att? I got the phone off craigslist and it doesn't to unlock.

tmobile gave me some codes but they don't work and I'm not sure if I'm suppose to have my sim card in there.

Any suggestions is greatly appreciated!! mods if this is not allowed pls. lock

Heard that the 6030 was tricky to unlock...there's 2 versions: easy and hard/impossible.
