Viewing wifi passwords?

I was wondering if I could view what my stored password is for an iphone wifi account. The situation is this: my iphone has a wifi password account saved (for the wifi at my uncle's house) and I'd like to add that same account to my wifi-airport for my macbook pro. I could just ask my uncle for the password again, but I was wondering if this is even possible on the iphone.

Thanks,
