I decided to take my new iPhone 3GS on the run today with Anne.  It is not exactly small enough to run with but I wanted to test out the GPS function.  My original iPhone did not have the GPS.  I used the MapMyRide application that recoreded the run.  I also used my Polar heart rate monitor with a footpod which I have previoiusly calibrated.  We ended up with 7.40 miles per the Polar and 7.42 miles per the iPhone.  Remarkably close.  The iPhone application also saved my workout and route we took, as you can see below.
