Clear, hard plastic case for iPhone, with a jaunty little stand built in.
The packaging didn't mention the 2nd generation, so presumably this is only suitable for the original one. That would explain its appearance in Poundland.
Maidstone's store had about twenty in stock, so good luck with your local store if you fancy one of these.
Currently available @ Amazon for £5.99.
Edit: Note ukcobra's experience with the belt clip...
"I purchased this a few months back, it is dreadful. The belt clip is very poor and it kept dropping off my belt, the last time, it damaged the touchscreen resulting in a 150 pound repair bill"
