Well, I was having a battery issue with my phone the last couple of days so I decided that I would restore it to factory settings. And I did, but there is some evidence that I did used to have an unlocked phone. For example, I used MIM (Make it Mine), and I changed my carrier logo to say Matt ... After I did the complete restore, it still says Matt, not AT&T. I don't know why this image wasn't restored.

What should I do?

I'm running on 1.1.2, I had 1.1.1, but I upgraded with OkToPrep.
