I live in MA but my iPad thinks it is in Clarksville, Indiana (both in Maps and other apps). This becomes annoying if I try to post in Facebook and all friends ask what I am doing in IN. This has been happening in both iOS 5 and 6.
I've read on the web where people claim this is because of the Apple location database thinks my wireless router is in IN but if I post a comment to Facebook on my wife's iMac (also on wifi) it correctly identifies my location.
I've also used my iPhone to determine my location while connected to my wifi which is supposed to update the Apple location database but it's had no effect.
Any ideas on how to fix?
