no provider-connection after updating to ios6
Hi,
i'm from Germany - where i got the iPhone 4s.
Currently i live in Japan. Some days ago the iPhone updated to iOS6.
After that I couldn't get any signal from my provider.
Chose the japanese provider manually, Restarted the iPhone several times.
Nothing happens. What else to do?
I need to fix it promptly!
iPhone 4S, iOS 6
