Canadian Short Code Texts? Please Help!

[boatdrinks]

I have an unlocked Curve on the Fido network, and it can't receive messages from places that use short code text messages (Twitter, the bus, facebook). I'm super frustrated because I looooove my bb, but my stupid old Nokia could handle short code.
I called Fido, and (unsurprisingly) they weren't very helpful - apparently its a compatibility issue, and not high on their priority list, unless everyone starts complaining. Is there a work around? I've done battery pull, I've tried every way of entering the numbers, and I'm at the end of my rope! Any suggestions would be super helpful. Thanks!

What texting plan do you have? I've never heard of this - I was with Fido and could receive shortcode SMS'.
