Show all email header fields?

Is there a way of showing all header fields on an incoming email? I have a Curve 8330. Thanks.

I think it can only done after opening the email. Press the berry button and select full header.

Thanks for the suggestion, however there does not appear to be any "show full header" option. At least not on the Curve.
