In the end, having tried a few things, I installed a free app called qr code (barcode for the app: http://db.tt/sNcfBdS) and used that to create and send a mail with it attached.
Again, a work around rather than a direct solution but thought I would share what I did. This has the limitation that you can't share contacts which you have lots of data stored for unless you only choose to share a couple if bits of info (which qr code lets you do).
The answer seems to be that you can't use your gmail unless you do so via imap, so i have marked matt h's as an answer.
