I'm really liking my 4S and iOS 5 (especially now I can hide news-stand!), however there is one tiny thing that's bugging me ... When I use find my friends the distances it gives me to my friends is in Km rather than miles. How do I change this to miles? My regional settings are set to United Kingdom and Google maps comes up in miles as do all my other navigation apps (apart from foursquare, not sure if that's related) Can anyone help?
