Is there a piece of hardware available for the iPhone that drives a radio trigger? For example, that plugs into the 3mm headphone jack, or Thunderbolt connector? I am a PocketWizard guy, so that's what I want, but if such a thing exists for another trigger manufacturer it could work.

I want to fire the Speedotron setup with the iPhone as the camera.

A PC sync cord implementation would work in principle, if it exists, but I would be concerned about frying the iPhone.

Googled and came up with lots of data but no information. Godox and Nova are not solutions. iSyncFlash app doesn't seem available anymore.
