Has anyone been able to set up data for 2degrees on a BlackBerry 8707v?

I emailed 2degrees to ask for further information than what was on their site (http://www.2degreesmobile.co.nz/settings ) but simply got the website info repeated in reply!

I have tried getting the setting sent directly to my phone from the http://www.2degreesmobile.co.nz/settings page and have also tried the same using the 2degrees SIM Menu. I have also manually entered the APN "internet" to no avail.  The BlackBerry still says "Data Connection Refused". The phone is not locked to a network.

Any help would be appreciated

P.S. Yes I know 2degrees data is currently very expensive - I won't be using it much on this phone! I just want it set up should I need to use it at any time. My main data use is on a Vodafone Data plan. =)
