Something I came across researching a completely different thing...

Apparently you can do some witchcraft with USB OTG (for power) and some other various bits of gear to use a *proper* mic on a phone. Not a total suprise (I mean, I do have USB powered devices on a PC that can run phantom powered mics) but its fairly neat nonetheless. With the right setup, might make an awesome mobile recording setup.

This is pretty neat ;p
