For my birthday my wife bought me an iPhone 4 and a phone holder for my truck, so I could use the iPhone hands-free whilst driving.?But she also bought the phone a protective case. Well, what d'ya know: the iPhone won't fit in the mount when its case is on. It was becoming a pain to have to take it out of the case each time I drove, so?I got my sugru out and modified my truck's phone holder. Voila! - It has worked perfectly for months now, and it was very easy to make. And, some say it looks cool! Jon, USA
