It should also be noted that the accuracy of the iPhone 4s's receiver is very good. The best I ever saw was from my iBlue 737 which maxed out at twelve feet. As I recall, my iPhone 3GS sometimes got as low as 32 feet but didn't maintain that for very long. I can't speak for the iPhone 4, but at some point the GPs receiver was apparently given a major upgrade, because my 4S more often than not shows 16 feet. Now this may be an apples to oranges comparison because the iBlue number was reported by a Windows Mobile software product, where as the iPhone data was interpreted by the Ariadne GPS app, but I suspect that both products are simply reading this from a data block from the receiver, hence these numbers are meaningful.
