iPhone 4 bike mount recommendations Can anyone recommend a good bike mount for the iPhone 4?

There seem to be a lot of reviews for the old models.

Update: I'm mounting this on a Trek 1.5 Triple with Bontrager SSR VR bars.

Update: I've heard horror stories about phones popping out of mounts so having it secure would be good, waterproofing is a plus as well.
Biologic now makes an iPhone 4 specific mount. I have the 3 version that I use an iPhone 4 in.  It's pretty decent, but this looks like they've made some good improvements.
