I've had the same issue since Friday night, in Chicago on my 900. Spent a bit of time yesterday trying to figure it out. From what I've gathered it seems to be an AT&T aGPS/location services issue. I've been able to remove the problem by turning off AT&T data (LTE), clearing map history, and using wifi. It's also fine when I'm outside and can get a GPS signal. As soon as I start using AT&T location services, all location-aware apps put me in Akron at 249 Firstmerit Circle. There are couple different threads for this issue on Nokia Support, and a rep said they would be looking into it. Hope this gets figured out quickly.
