cgriffin21 writes "Microsoft on Thursday released the final Windows Phone 7 developer tools to manufacturing, giving coders a couple of weeks' lead time to get their apps ready for the launch of the Windows Phone Marketplace in early October. Microsoft released the Windows Phone 7 OS to manufacturing on Sept. 1, and its OEM partners are in the process of testing it on handsets. The Windows Phone 7 developer tools are the final piece of the puzzle for Microsoft, which is now ready to march back into a mobile market where it has fallen alarmingly behind the leaders." In related news, CNET reports that Windows Phone 7 will only be available for GSM networks at launch, with a CDMA version planned for the first half of next year. This rules out Sprint and Verizon for launch.
