So I searched the forums but didn't see anything related to this but I've noticed that my iPhone 4S has worse GPS accuracy than my 4. I notice this most in the Garmin navigation app (the on board maps version). It doesn't even show that I'm on the road and in just map view it just says my direction where it used to say direction and street name. Anyone else notice this too? Maybe it's just capability with iOS being the issue? The maps app doesn't seem too bad but that doesn't do turn-by-turn Thoughts?
