Recording on iPhone with Blue Yeti?

I'm a voice actor working off a very noisy laptop, and would like to check out the possibly of somehow hooking up my USB Blue Yeti microphone to my iPhone 4. I saw somewhere online that someone had used an adapter from some sort of kit to achieve this, but I don't really even know where to look for purchasing one or if it even exists for the iPhone.

Not on a stock one.

You would need to get an iRig or other input, phantom power injector, and XLR version of the Blu Yeti or other microphone.
