I have for sale a brand new Brodit Proclip for an iphone (it was for 4/4S but given the iPhones are all the same width I'm sure it'll do a 5S or 5C just as well.
I've attached the web page link for it so you get the idea for it and a photo of the item when it's installed in the car ..
I ordered the wrong item and too much hassle and expense to return.
An expensive item up for grabs at a cheap price of £20 ono (posted).
Full details regarding the holder are found here http://www.brodit.com/product.html?id=654046
