I vote for the 3.5.  Supporting standard headphones is more important
than being able to use a wired headset.

However, some phones (at least the ROKR E2, maybe others) have had a
3.5 jack with an extra ring, which I think is for the microphone.  If
you follow this standard, the wired headsets designed for those can
work.  You can plug in standard stereo headphones (in which case the
sleeve shorts out the microphone input) or the special wired headset
with an extra ring.
