MP4 is a container format and can hold video and audio streams in several
different formats, with several different codecs.  You may have to dig out some
documentation on your (non-i-) phone to see exactly what it supports, then look
for overlap with the iPhone.

This may be of some use to you:

This might help you convert files from one codec to another:

Or ffmpeg from various places, including:
