My router has the ability to support wifi channels 12-14... should I do this cuz it's MY device? No, the FCC would not like it if I did, and if they found out I was, i could get into alot of trouble for pirate radio(maybe not technically, but simply enough yes). Would they Know? probably not... Doesn't mean they can't and won't.
Same applies to cloning ESN's... except these devices are tracked, unlike my wifi router.
