^^ all true.. like he said though if you ever exchange it or trade it in, they may check that.. ive returned them and theyve not checked but ive also had the guy turn it on and check the firmware before so it depends on the person really.... i know they don't like me at the gamestop around the corner cause i went in there with my hacked psp one day and the guy was like 'i can't talk to you' after commenting on how cool my theme was lol.. if you ever have to, do returns at walmart.. most likely they will be stupid about the whole thing and take it back
