MetroPCS Communications Inc, a Dallas-based wireless carrier, is allowing customers to bring phones from other carriers to its network. Supposedly this is one of the largest carriers to do such a thing. Analysts say that this will be the trend as the US wireless market starts to open up.
That said, if you think you can activate an iPhone on MetroPCS Network, it’s not going to happen. They use CDMA, so only phones from Sprint, Verizon, and Alltel Corp will work.
