This MobileSubstrate library can trick any application into thinking that it is on Wifi even though it is on a cellular data connection. There are a lot of possible uses for that, but for me the main use is being able to use VoIP programs like Fring over 3G. You can configure what apps get tricked by adding the app’s bundle identifier to “/Library/MobileSubstrate/DynamicLibraries/VoIPover3G.plist”. Currently, the default is to trick only appstore and fring. If you remove or rename the VoIPover3G.plist ALL applications will be tricked. This is not recommended though, because for a lot of apps its makes sense to know whether they are on wifi or 3G.
