I just happened to be looking at the Facebook Blog today and found this article about 0.facebook.com which is a stripped-down mobile Facebook portal offered as an unmetered service by 50 mobile operators worldwide. Down at the bottom of the page it says it will be coming soon to Telecom NZ.
Haven't seen anything announced by Telecom to this effect, but this is a much better partnership for Telecom than Bebo so I'm sure they'll make a song and dance about it soon enough.
