iOS 4.2 beta 3: Is the App store working for you?

I installed the beta 3 yesterday night and everything worked great. This morning I accessed the App Store without any issues. Now I am at a customer and when I try to access the App store a connection error comes. I have the Wifi iPad, so I am not sure if it is just a problem of the Hotspot I am using, especially since I could connect to the AppStore earlier today from home.
I have an account in the german AppStore. Does anyone have problems connecting to the AppStore from their iPad?

Ok, it was the Internet connection. I switched to a different Hotspot and everything works
