This is a stand for your iPhone that lets you view in either portrait or landscape mode, so it's great for videos. It works with both the original iPhone and the 3G version.
It's £22.99 plus £2.11 delivery, but you can get a £10 off £20 voucher until the end of the year using the attached deal, bringing the price down to a more reasonable £15.42 delivered. It's £29.59 delivered on the Apple Store site!
There's also a version for the second-generation iPod Touch, at the same price.
