Really? What function did it serve the iPhone?

  Likely just simple glue logic. Things like converting one protocol into another, doing some multiplexing or some simple pre-processing or filtering on some sensor data. They're incredibly tiny (2x2mm) and use little power, so they pop up in designs pretty regularly.

    I wonder if they are reprogrammable, so if what's running on these could ever be updated.
