When I received my iPhone I was surprised by the very few cosmetic flaws, mine being a single dent in the top right corner of the phone. I was however surprised when the phone was locked to AT&T. While I knew that this phone was an AT&T model I did not see that it was locked to said carrier. I did however find that is relatively easy to request an unlock from AT&T and I got my phone unlocked for free within a day of requesting the unlock. I have included the link to request an unlock from AT&T in case there may be other customers like myself trying to use this phone with another carrier. https://www.att.com/deviceunlock/#/
