As a last resort you can always restore the iPhone in iTunes.

You should also check online whether any of the Problems and Solutions apply to your situation.
And, of course, you can contact bSE (also accessible from the Help Menu.)

If the iPhone is not recognized by iFuntastic, or worse, iTunes, or worst, your computer, then you can try various methods to fix that. Often a general messing around gets things going again - for no apparent reason.

Each of the actions below has been found to help in at least some circumstances.
In order of increasing desperation:
  • unplug and replug the device
  • try another USB port
  • restart the device; either manually or with the provided function
  • quit iFuntastic and delete its preferences file: ~/Library/Preferences/com.bSE.iFuntastic.plist
  • quit and restart iFuntastic or iTunes
  • restart your computer
  • put the device into DFU mode and restore
  • try another computer, if possible
  • reinstall iTunes
  • reinstall the operating system
