Those presets should work for iPhones, with several caveats.  They just
set the h264 profile, level, maxrate and bufsize.  These values may or
may not be optimum for your iPhone, depending on the model, but
they should work.  The presets do not set the codecs necessary for
either iPods or iPhones (generally libx264 and one of the aac
codecs, as you were using), not do they scale the video within the 
maximum specs of the device.  You can look up the specs for the 
iPhone you have in mind and make sure that you have the correct 
parameters in your command line.

I'm not aware of an "iphone" preset.  You could easily make one by
editing the ipod preset to fit your specs.  When I tried that the 
presets seemed pretty limited as to what options you could put
in them (for example, scale, codecs, etc. don't seem to work)
