Incorrect SIM This phone must be used with an aprroved SIM

[Connecticut]

I dont understand, my SIM is a valid AT&T customer. It worked in the iPhone untill I update by ACCIDENT, before I even knew about the 1.1.1 upgrade. I did the whole reunlock process and got Incorrect SIM This phone must be used with an aprroved SIM.

Again I am a valid AT&T customer, I even have my sim in another cingular phone and it works fine....whats the problem here?

I heard something about a Baseband but I still dont understand why it wont work in the iPhone but in my old cingular phone.


Any suggestions, please help.


I've been following the DEV team but have heard nothin....

Cross your fingers and hope for a 1.1.1 unlock asap :)

They're well on the way towards it...

Take it in. You get one (I think up to two) replacement sims a year for free.

Did you unlock your phone? Because if you did, regardless of the sim it has installed, it will tell you its the incorrect one.
