There’s good news and bad news for the Windows Phone 7 homebrew community. The good news is that the developers who brought us the ChevronWp7 tool for sideloading applications on WP7 devices have been talking to folks at Microsoft who say they support independent and homebrew development for the platform.
The bad(ish) news is that as part of these discussions, they’ve discontinued the ChevronWp7 unlocking tool, which means the only way to load apps on your phone that aren’t available in the Android Market is to pay for a developer account and use Microsoft’s developer tools.
Even if you’ve already downloaded the ChevronWP7 tool, it will no longer work properly because the certificate required for it to run isn’t online.
