On yet a different phone platform we experimented with several different schemes. We found that people pretty much always felt that pushing a "+" at the top to go up and a "-" below that to go down was most natural. When you introduce a wheel, however, things get a bit more muddled -- usually going up seems to be the "positive" direction, but sometimes down seems "positive", depending on the context. And if the wheel in turn is controlling a scroll (vs using "kinetic scrolling") it becomes even more muddled, with pretty much a 50/50 split, and individuals even changing their minds from one trial to the next (usually preferring, of course, the scheme they're not currently testing).
