I went on AT&T's website to see if I could get it unlocked again. When I enter in the IMEI number, the web site says it doesn't recognize the IMEI number. It had showed up before when I tried. I also have a Blackberry Z10 that I swap the sim card with. I bought the Z10 after the Lumia 925 and they changed sim cards from the one I was using. I had forgotten to bring the sim card with me, so they put a different one in. And deactivated the sim card that was at home in the 925. I wonder if that's why I couldn't get an unlock code from cellunlocker, since AT&T didn't recognize the IMEI number, they recognize the Z10 now. I really don't want to call them about that, they may screw it all up.
It really doesn't matter that much right now if its unlocked, I'm using GoPhone, and a Straight Talk sim, so both phones work just fine since they are on AT&T's network. It's just the principle, its my phone.
As far as it being subsidized, I don't consider walking into an AT&T store, paying full price, off contract, for a phone, to be subsidized in any stretch of the imagination. I didn't buy a GoPhone.
