Yesterday I updated My iPad 2 from iOS 6.1.3 to 7.0.3 and found that location services were turned on but on opening maps it said cannot determine location.Didn't had any such problem in iOS 6.1.3(I have wifi only iPad)
I also have an android device which is able to locate me correctly using the same wifi.
