Its on MDL firmwire with TWRP and currently running AOKP, in my experience its not easy to come by an AT&T on MDL anymore..
I'm located in the (845)/Hudson Valley area in NY. I won't ship the phone. You can message me if interested, its in mint condition and comes with the original box, charger and a nice case. Phone is black.
I'm looking for a second gen nexus 7 BTW, preferably 32gb. $250 cash gets it.
PS: If this isn't allowed a mod can just remove it.
