I tried my XT SIM in my iphone then put my Vodafone one back in. "Telecom NZ" was stuck there, instead of having VodaNZ there.
So, I restored the iPhone (3gs) and installed the carrier bundle from iPhoneNewZealand.co.nz - still the same problem.
Has anyone worked out a solution for this? (Other than restoring the iPhone).
I realize its just a little thing, but it bugs the hell out of me, I don't really want to have to restore my iPhone each time I use my XT SIM.
