5.1 beta fix the network problem that iPhone 4s was having in some country. Some sim wasn't working on 5.0 or 5.0.1 iOS . But now all cellular network is working just find.
Sorry, but unfortunately not. The information is classified for non-paying developers. Apple is harsh on disabling accounts and I do not want mine suspended.
Maybe someone else can?
