It took a bit to extract all the necessary data the right way, and some little things like getting the back button to work correctly held me up.
I wouldn't have clicked it until looking for a back button. Might be worth leaving it as text, and maybe placing a back button to the left of it? Personally I think something similar to the back button in Windows Phone would look nice. Something like the button here: http://i.msdn.microsoft.com/dynimg/IC505392.png
