Hi
i have a new N900, the tech center replaced my 1st one to new one because of a serious problem with USB that didn't work. So yesterday i set everything up again and noticed, that with a 3G/GSM/Dual switch widget i cannot switch network mode.
I then went to SETTINGS > PHONE and noticed, that no matter if i change something and then save it, the next time i return to phone settings i still see the same old setup.

Can you help me and explain what i can do to have it changable?

Thanks
