Now we can not recommend this tweak but if the release of Slingplayer without any 3G support got you down, you can be Happy!

Tricker ThreeG is a small tweak available in Cydia that allows you to use the SlingPlayer connection using 3G data network. It simply applies the same patch of VOIPover3G but does not require the modification of files or the addition of indentifier bundle.

We do want to Warn you against the use because it adds a new daemon process in the background, so if you already use VOIPover3G, you can continue to use only one, with appropriate modifications.
