Shouldn't be impossible to make a »sleeve« like that, but i don't think
it exists. Neither does a 3.5mm jack to 2.5mm plug seem to exists, even
less imaginable is it that it would support 4 conductors (stereo +
mic). But as soon as it is reasonable to mass produce them some company
will. And in the meantime i am certain that there is some one in you
local OMG/LUG/UUG that have at least basic soldering skills.

The parts needed cost ca. 4-6€ in Denmark at the local RadioShack
(Brink Elektronik or what ever your local eletronics store is called!)
