When Windows Phone 7 arrives later this year, it will be sold globally, but only for GSM networks. Microsoft has opted to delay until next year the CDMA version as it works to finish work on its major rewrite of its phone operating system.
"We had to make some trade-offs," senior product manager Greg Sullivan told CNET today. "Even Microsoft doesn't have unlimited resources. We had to prioritize doing fewer things, really, really well."
The company made the decision to delay the CDMA version earlier this year but had declined to publicly confirm it until now. While GSM is much more widely used in Europe, the decision means that Windows Phone 7 won't be available on two of the four major U.S. networks at launch--Sprint and Verizon.
