My friend gave me an original iPhone, it is an American iPhone but would it work in the UK if I unlocked it? I'm planning on selling it as I have an iPhone4.
Not necessarily true in the UK or most of the rest of Europe. Networks can and will unlock them, usually for a fee. Different networks have different criteria.

A network cannot unlock an iPhone that is not a part of it's network. Example: Orange cannot unlock an AT&T iPhone. Thus, in response to the OP's question, a jailbreak is needed.
