I'll do some looking around, there might be a good post in the General Discussion forum that shows some really good options. Theres a company that was linked in the thread and they had some great options. They had a bracket that was very clean looking and actually mounted to the A pillar on the left side. I'll see if I can find it.
Found the website, not the thread.

The one that clips onto the A pillar is what I would get if I used the iPhone. Get the one that swivels and has the cigarette lighter. Around $100 for the mount and the holder, but it looks clean and worth the money, in my opinion.
