Voice over IP

T-Mobile made a big deal about being one of the few carriers embracing open standards and open systems -- which is true. Yet just how open is a (sorry) open question. When I talked to Cole Brodman, the CTO of T-Mobile, after the event about what would stop something like Skype from designing a program that could run on the phone, negating the need for a massive voice plan, he said he had "worked with Google" to make sure Android couldn't run VOIP. "We want to be open in a way that consumers can rely on," is the way Brodman put it to me.
