Not long ago, Windows Phone 7 was blessed with its own jailbreak/unlock tool. Titled ChevronWP7, the app would allow users to sideload apps that normally wouldn't make it into the official Windows Marketplace. If you own a WP7 device and were planning to get your hands dirty with some unofficial apps, hopefully you downloaded the tool before today, because ChevronWP7's creators have yanked the download links from its site. After being contacted by Brandon Watson, Microsoft's Director of Developer Experience, the team has agreed to discontinue ChevronWP7 and its development in order to fast-track discussions about Microsoft officially giving the a-ok for homebrew on Windows Phone 7.
The fact that Microsoft is willing to consider embracing homebrew on Windows Phone 7 is great news, especially considering how opposed some of their competitors are to the jailbreak/unlock scene. Even if Microsoft does allow some form of homebrew development with WP7, I wouldn't be surprised to see it come in a much more limited form compared to what it could be if ChevronWP7 were never pulled. Still, it'd be wise for them to allow some sort of hacking. Considering how young WP7 is, it could use all of the support that it can get.
