When we all first figured out how to unlock the gps on our Vogues and Moguls and before Shadows fix popped up the gps was to say the least unreliable. But once 6.1 came along and the agps fix popped up it worked awesome!
I seriously doubt you have a hardware issue, your phone alone just isnt a very good gps reciever without data to help it along.

If you are ever able to get a data plan you will see what I mean, the Mogul is capable of very impressive and reliable gps signals.
