I wanted such a thing for a while, but didn't see it in shops. But when I bought car holder it occured, that construction with two plastics claws covered with rubber can hold phone very good if you press them 3-4 clicks more.
After that I've bought second holder made by onext (this was the first model offered in a shop). It suits good by it's size and claws beside rubber have projections on their side, which prevent phone from leaping out. Disassembly was accompanied with cracking and flying springs. As far as handlebars stem on my bike is square it was sufficient to press the holder to it. I've made four pairs of holes in holder and attached it with strainers to the stem.
My experience shows, that phone is beeng hold firmly, it doesn't move even while speed ride through the forest with jumping on roots and pits.

does this work?
How smooth are the roads there?
When I have a holder like this it pushes the camera button all the time, and still the n900 jumps out. I put rubber bands over it but it still vibrates so much that I don't trust it when going at higher (>30 kph) speeds.
Roads in the town are good.
Roads in the town are good. Road in villages and forest are bumpy or horrible. And I ride on speed about 20-30 kph. So phone is being hold firmly. Rubbers on my holders are not solid, they are onlu near sides of the claws. So there is some space in the middle and camera button fortunately is not pressed by them.
Rubbers are thick and soft, so I can make 3-4 clicks while I completely compress them. This gives enough grip to hold the phone.
