I'm a complete n00b to the freerunner, I don't even have my phone yet, but
for saving power when using GPS is there a quick way to turn off GPS when it
is not needed and back on that will cut down on power usage, also delaying
when it updates might help two of my friends have an Iphone and they update
GPS every 2-3 seconds I don't think setting a delay in the updates would be
such a bad thing here as long as it is not something insane like 10 seconds
