Ahh I see. I guess some people may buy cheap dedicated android phones second hand off eBay or perhaps one of the cheap Chinese tablets to mount on bike.. I'm thinking about doing that myself rather than using my beloved HTC Desire phone..I've not had any luck finding a secure mounting solution and neither am I very confident about using a DIY setup incase it falls off ;-)
how about this
