Question

For an iPad, or iPod touch, is there a way to find out if the device has GPS?

Answer 1

Download altimeter or similar app. Turn off cell data and wifi before you ever use the downloaded app. Then launch the app and see if it will give you Your current altitude. If it works you have GPS if it doesn't then you don't
