I just received a new FX100 that I ordered from a dealer on eBay. the package came factory sealed, but it seems that the unit may be old stock. How do I update the firmware on this thing? The not-really-a-manual that come switch the unit states that it is compatible with iPhone 5S, 5, etc. can the update be done directly from a desktop computer via USB cable? i just spent a couple hundred bucks in this damned thing and had better be able to use it...
