"With that in mind, we will work with Microsoft towards long-term solutions that support mutual goals of broadening access to the platform while protecting intellectual property and ensuring platform security," the ChevronWP7 team wrote. "In the meantime, a forthcoming Windows Phone 7 update will fix a bug that the ChevronWP7 unlocker tool took advantage of; the tool will cease to work thereafter. To fill this short-term gap, we're collaborating with Microsoft on an interim solution that will continue to support homebrew developments after the update. We will share details of this when it has been finalized."
Two months ago, ChevronWP7 was discontinued less than a week after its release. ChevronWP7's three developers, Long Zheng, Rafael Rivera, and Chris Walsh were approached by Brandon Watson, Director of Developer Experience for Windows Phone 7, and decided to kill their app. In return, Microsoft agreed to allow them to become more involved with the shaping of the homebrew scene on the Windows Phone platform, but emphasized that ChevronWP7 would not be the way to do so.
