Q: how do you reset carrier settings on iOS 8.1 ?

it is definitely not, i tried running terminal, making it able to install previous carrier settings on the iphone via itunes but all the guides from previous OS´s seem to not work.
I tried to reset network settings on the iphone and putting another simcard on it hoping to get the options back advertised on iOS 8.1, but unsuccessfully.

Does anybody confirm that erasing the iPhone brings back standard cellular settings ?

also, keep in mind that mine is an unlocked phone, i didn´t buy it from the carrier, so i see no reason why they should be allowed to mess up my phone.

i do have backups, but i guess they´re contaminated by 3 hutchinson austria and their settings.
The problem is that if I set the phone as a new phone, i would have to put a simcard in it and it would download their settings right?
