i started playing with my iphone a couple of hours ago and everything is working perfectly except for GPS! location based services on, but no application (including maps) can find my location. the little spinny thing just keeps going and going. i've turned location based on and off, the phone on and off, and reset the phone, much to no avail. also, i was inside, and tho i had full service, pogue said that nyc buildings cut GPS so i went outside to an intersection where there was space in the sky and still, NOTHING. it's as if my GPS chip doesn't exist. any ideas on anything else to do? i'm sensing a trip to the apple store tomorrow and i'm not happy about it!
