Microsoft says manufacturers sold carrier partners over 1.5 million phones running Windows Phone 7 during their first six weeks on the market. "In the U.S., only two carriers currently offer the GSM-only phones: AT&T and T-Mobile," notes ZDNet's Mary-Jo Foley. "In early 2011, Verizon and Sprint are expected to begin selling CDMA Windows Phone 7 devices."

Foley suggests that sales would likely have been stronger if phone makers and carriers provided sufficient stock. "Or," she adds, "if phone makers didn't have to delay shipping models with various technical glitches." Microsoft is expected to deliver an update to the Windows Phone 7 operating system in early 2011, which will add support for copy and paste, along with various new functionalities. Meanwhile, Foley's sources have indicated that a major operating system update, codenamed "Mango," is coming in the third quarter of 2011 and will include support for Silverlight and HTML 5. In a statement, Microsoft said it plans to "push Windows Phone 7 software updates to end users and all Windows Phone 7 devices will be eligible for updates."
