You can use the watchPosition method in PhoneGap's geolocation library to add an event listener for significant location changes. You could then do some fairly simple math in the callback to figure out distance. Don't forget to use geolocation.clearWatch to stop watching the current position when it's no longer needed — geolocation can drain a device's battery quickly.

Note that both "`watchPosition` method in PhoneGap's geolocation library " and "fairly simple math" are links – OverlappingElvis Jan 31 '14 at 00:18
