Mobile phone tripod mount?

[squirrelproductions]

Anyone ever use a mobile phone tripod mount? I'm looking at something like this eBay auction for use with my tripod. Anyone have any experience with them with their Nexus 4 (or other similarly sized phone)?

I did try those showed above. The height seems too short for my HTC 4.2" device.

So i DIY one for myself.
