Change GPS

Do you mean similar to faking a different phone number (showing up on Caller ID)? The only people I know of who do that are not exactly trustworthy, so why would you want to fake your location? What if you have an actual emergency - do you want them to look for you in Timbuktu rather than where you really are?

FWIW, I don't know of an app that can do that - you can just turn off your phone/car GPS.

This isn't possible....Not without doing things such as jailbreaking your iPad which there still may not be a way, and that isn't allowed to be discussed on the forums either so if there was a way (which I'm pretty sure there isn't) we wouldn't be able to help you.

You do realize that you will void any warranty if you decide to do that.
