Always use 3G, even with Wifi connection
I recently acquired an iPad 3g + Airport Express.
The only internet connection available is the 3g iPad connection, the wireless network only exists to stream music to speakers, but does not have an internet connection itself.
Difficulties occur when the iPad connects to the wireless network, because it wants to connect over wifi, which doesn't work.
Is there any setting, which would force iOS to always connect to the internet over 3g, even when it is connected to a wifi. It should at least realize, that the wifi connection doesn't work and then try the 3g.
Is this doable with iOS?
Thank you for any useful input
