How can I forward a Text Message / SMS?

Newbie here trying to figure out workarounds for SMS forwarding. So far no luck with a first post to the board. Hoping someone can tell me what they do for this issue:

SMS FORWARDING - I’ve been fighting this one for days now that I own the phone. My BB allowed me to forward as a SMS, Email or even a PIN (to an IM client). How can I do this with my new iPhone? Is there an app or trick I am missing?

Thanks for your help.
