How to view my saved password

[Mgallagher]

Hi all, so I have access to someones iPhone and they have their mail password stored in there. I know they use the same password for mail and facebook, so I need to find out what said password is. When I go to view it on their phone, it's in asterisk form so I can't view it. Is there anyway I can see what the actual password is? I've tried the deleting one letter then undoing it trick but that doesn't seem to work, maybe they fixed it with a certain update. Either way, any help would be greatly appreciated. And before you get on the whole moral dilemma rant, if I wanted moral advice I would go to a church forum, this is a technical forum so that's all I'm interested in. Thanks again.
