Are there bugs with Find My iPhone on the 4S?

On a iPhone 4S with Verizon service you can track where location services are being used under Privacy/Location Services… The Find My iPhone has an arrow by it saying it has been used… But it HASN'T been used, so why would it give the designation that Location Services is using it?

It always checks once in a while so if your phone lost service before it was lost/stolen at least you would have the last location it checked. You can't turn this feature off unless you turn off Find my iPhone completely.
