Can i use the same case for my ipod 5 as my iphone 4?

Okay so i was on ebay looking for cases. So this one person had iphone4/ipod 5 cases. So does this mean that you can use the same case for an ipod 5 as an iphone 4? Will it fit the ipod or is it too thin?

I'm pretty sure the iPod 5 is longer than the iPhone 4

I don't own an ipod but how the hell should it matter what caste you put it in, i mean seriously!

I don't think so since the iPod touch 5g is taller than the iPhone 4. I think they mean they have separate cases for both iPhones and iPods.
