For the marzipano tool your image needs to be in exact 2:1 ratio, that
is the width in pixels must be double the height. And it must be in
equirectangular projection. I don't know what the iphone produces, but
decent stitching programs like PTGui (commercial) or hugin (open source)
give that output. They also can convert between projections...
