Torpedo Live -> iPhone

Hi,
this is my first question here. I would like to record some YouTube videos with the Torpedo Live. To do this I would like to go directly into an iPhone that stands on a tripod. What would be the best or recommended way to do this with the Torpedo Live. I assume there needs to be an analog to digital interface that plugs into the iPhone.

best would be to get an iphone interface like iRig which most music stores have and then just run a standard 1/4" cable from Live out to the 1/4" input

Thanks for that. I will try this now.
