I'm using https://ookoo.org/iphone/iasign.php custom activator v0.2 and i've double checked my ICCID, Device ID and IMEI before generating the activator v0.2. When i run it i get a ICCID mismatch error, and the phone will not activate.

It is Jailbroken, and unlocked with anySim1.1p. When i put the AT&T sim in it i get past the activation screen, but when i put my sim in i get " A different sim has been detected, please connect to itunes" and when i connect to itunes i get the message that the Sim is not a valid AT&T sim.

Is this an activation issue or an unlocking issue. Mind you that anySim1.1p said is successfully unlocked the phone.
