If you are on Windows, give MediaCoder ( 
http://mediacoder.sourceforge.net/index.htm ) a shot. It has a pretty 
clean interface, and has product specific to the iphone that gives great 
results. It's based largely on mencoder, ffmpeg, x264, mp4box, etc but 
wraps it all up in a pretty good gui. If you are on Mac, I would 
generally suggest VisualHub (http://www.techspansion.com/ ), but as that 
product has been discontinued, and it's replacement ( 
http://sourceforge.net/projects/transcoderredux/ ) seems to be still in 
the early stages, I'm going to suggest that it might be easier for you 
to run MediaCoder in Parallels or VMWare Fusion. VisualHub might be 
found in some of the more disreputable places on the net. There's also 
ffmpegx ( http://www.ffmpegx.com/ ) but I don't like it as much as 
VisualHub. :)
