I've just received a Vodafone "Broadband Complete" modem/router and have set it all up.  Everything is working fine, a very nice piece of kit, but I thought I'd just check that it's running the latest firmware for it.

I found this page on the Vodafone website that talks about an update to the firmware for this modem, but unhelpfully it doesn't say what version is the latest.  There's a download link which goes to http://www.vodafone.co.nz/broadband/firmware%20 but this comes up with a 404 error, probably because of the %20 on the send of the URL.  If I remove the %20 from the URL then I get a page that says "Method Not Allowed" and that's all.

Accoding to the modem it's using Software Version V100R001C12B037.  Can anyone tell me if this is the latest or where I can look to find the latest firmware?
