Know what? G1 data plan is not compatible with my voice plane and they can not add it to my account! Just great! I have an old one and really cheap one National Business Plan 300 plan (300 wherever + 300 mobile + 100 msg for $29, pretty good). Don't really want to give it up, but that's not the thing! WHH, why should I change my voice plan now, it was never ever written anywhere that I have to had some special voice plan to use the G1. Of course I haven't read the agreement, but I am pretty sure it's not there. And I paid for that G1 data already. It's really wired.
