Nice idea for a program but...
If your phone rings, iTrails cuts out.
If you receive mail, iTrails cuts out.
If your iTunes needs a selection, iTrails cuts out.
Often starts off with .26 miles or more making accuracy suspect.
Has tracked me walking at 11 mph (I wish!).
Given that this needs a iPhone G3 to work and a G3 receives phone calls, emails, and is an ipod, this application is lacking and should not be charging $ AND should be refunding the monies it has collected.
