Probably this is what's happening with the Iphone EQ. The data is added to the audio, then goes through the DAC. The audio itself has been changed at the fundamental level. Amp or no amp the EQ isn't affected.
Please correct me if I'm wrong anyone.

Most digital source's volume is also digitally controlled too. Actually there is probably volume control (similar to an amp stage) in the DAC stage, but it is digitally disable to give a line-out signal. Now some might mistake that line-out must mean no amp, but there real thing is a little more complicated than that. The only requirement to be a line-out is that signal must be in line-level. As long as it is on line-level, it is a line-out (of course some line-out might be better than others)volume cant be change from iphone when using the LOD but the equalize can...goto setting > ipod > Eq and change while you are playing a song..u will hear the different..that is the reason it make me wonder if the LOD on iphone 4 is really bypassing the iphone 4 internal amp or not..
