The 20 cents a minute calling should cover the VoIP feature on T-Mobile phones, right? I've checked the bills from when I was in Hong Kong and Guangzhou, and was not charged for any of the calls I made, since they were all over the Wifi/VoIP at the hotels I was in. Anyone else see this? Because if that is how it's going to be, I am going to be a happy T-Mobile customer for a long time.
