I use a piece of software called (oddly enough) "Shutter Count" and I want to say it was by a company called "Dire Studios".
It wasn't "free", but it wasn't particularly expensive... I seem to recall it set me back by about $2 (the price may have changed... but I didn't have to make too many adjustments to retirement plan to be able to afford it.)
Being able to retrieve the shutter count is only moderately useful... it is not necessarily an indication that a shutter is ready to fail (there are lots of cameras that go well beyond the expected shutter life and there are shutters that fail well short.)
