What does Cydia do when you try to launch it and install applications when connected to 3G? It should work just fine.
Cydia says "Could not activate cellular data network" because i'm not connected, because i can't configure my cellular data network settings, because those buttons are on top of the screen and the screen is out of this world.
i just need to get that Activator app to work, but somehow it doesn't happen over PhoneDisk and .deb files install.
