I recently bought a line 6 mobile in since it allows stereo input to the iphone 5. I stream usually using my laptop and the phone as the network connection, but there isn't a jailbreak yet and i refuse to switch to a limited plan. What I would like to do is connect mobile in, has the standard dock to a lightning adapter, would it be possible to modify a lightning cable to get power from AAs or 9 volt batteries at this point to keep the phone from dying. This would be a temporary solution for me until the jailbreak comes out.
I wish that the mobile in had a external power supply
