I just recently returned my iPhone 4 to Rogers Wireless and they sent me a refurb unit. I've never seen this message "congratulations your iphone has been unlocked" before....I've restored a lot in the past too. Does this absolutely mean I just got lucky and they sent me a factory unlocked iPhone? I didn't purchase an unlocked unit on release day back in late July so I'd be super surprised if they actually sent me a factory unlocked unit. Can someone confirm for sure either way? Is there something in the model number or imei I can check to confirm if this is in fact a factory unlocked model?? Thanks in advance and happy Easter everyone!
