On Friday, I learned that Lumia 1020's in countries like Canada and India were getting the Cyan update. I got the idea that if I unlocked the phone and set my location to Canada I would be able to get the update.
AT&T approved my unlock and I tested it with a T-Mobile SIM card. I still can't get the software I want.
When I turn on the phone, it still says AT&T. It still lists AT&T as my carrier in Settings.
I've tried doing a factory reset and I've tried using the Nokia Software Recovery Tool to restore the factory image. It still says AT&T.
I need it to be completely carrier unlocked. Anybody have any ideas on how to remove all traces of AT&T from the phone?
