2.5mm or 3.5mm

[Nadav]

3.5, definitely.
And continuing the earlier comment about Nokia - the N95 (and possibly other
models) has a very interesting 3.5mm connector that provides much more than
just sound.
If a 3.5mm headphones are inserted, it plays regular stereo. However it
also  accepts the more advanced connector of Nokia's provided headphones
which also have a small console to control volume,
play/stop/forward/backward, etc.. That one has 4 contact points and not 3
like in regular stereo headphones.
It even supports video playback - there is a cable that comes in the box and
uses the same connector point to output several video types.

Sometimes the phone detects the plugged device automatically (I guess if it
supports some Nokia standard), and if it doesn't recognize, it provides the
user a list of options to choose from (headphones, tv-out cable, music
stand).

Just a thought...
