I have a problem unlocking my Iphone4
I have tried almost everything found on the internet
redsn0w 0.9.14.b1
blackra1n
absinthe 2.0.4
even tried JB then running ultrasn0w, and even ultrasn0w fixer 5.1 AND APN in cydia - unlockit.co.nz
But nothing seems to be working.
For starters I have NO clue what carrier it is locked to, a friend gave it to me after have been in his drawer for about a year. probly not containd leagally.
I live in Denmark som not an AT&T problem. . . I am willing to try anything here.

oh and just to add black to gray. . IOS 5.1.1 ....
