Here's an ad for one of the Chinese iPhone clones. While my Chinese is a little rusty, and when I say rusty, I mean I have no idea what these people are saying. It seems the Chinese iPhone has shake and talk.
From the look of the video, you just shake your phone to make a call, answer and hang up the phone.
If anyone out there wants to translate in the comments, that would be grand.
