Someone I work with needs a completely hands free blue tooth for the iphone 4. He can't use his hands properly so can't press a button on it to answer. He says he's pretty sure they exist but been to a few phone shops and they can't help. Is there such a thing and if so where does one get one?

The only one I can think of is the BlueAnt Q2 (http://www.blueant.com.au/q2/). It has a comprehensive set of commands, including "answer" and "ignore" for when a call comes in, and "phone commands" for activating voice dialling.

CNet gave it 4/5 (http://reviews.cnet.com/headsets/blu...-34145281.html) so it seems pretty good. It costs around £80, I guess that sort of utility doesn't come cheap.
