Thought these might be the Product-X style mounts for filming, surely there's a market for phone holders for filming for other phones apart from iPhone.
I noticed these the other day >
http://www.optrix.com/store/optrix-photoprox/, not cheap though and must as well buy a Go-Pro if you are splashing out money.
Anyway, tried out the Optrix filming apps on my iPhone in Morzine, the freebie version doesnt do a lot more than the standard iPhone video app, although you can change resolution which saves space, (I changed from 1080 to 720), the pro paid version is interesting as it adds speed, g-force and a small map but is rather buggy, I gave up with it, but got it to work once (yeah I know its out of focus).
