Can you locate a iPod or iPhone... Do they all have a gps in them
Iphones have a tracking system installed in them, which cannot be turned off by normal means, you can be tracked by the phones specific ID which is unique to the person who bought it, and as long as the OS stays intact it will work, Jailbroken devices on the other hand cannot be tracked as the the code is changed and it automatically blocks the internal GPS tracking system.... but you can install third party GPS applications that work the same :O
Not anything that has internet has gps on it dude))) Most of them do but this is optional hardware and it's not always instaled.
Anything that can use 3G or 4g network has gps forsure, not sure about the ipads. But it can be switched off.
