Homebrew apps coming officially to WP7... at some point
The team standing behind the ChevronWP7 jailbreak tool for WP7 announced that after a meeting with Microsoft they decided to discontinue the unlocking tool effective immediately.
In return Brandon Watson, the Windows Phone 7 Director of Developer Experience, agreed to "open the Windows Phone 7 platform for broader access to developers and users". In other words, it's only a matter of time for home made apps to come to the Windows Phone 7 (as opposed to apps delivered via the Marketplace).
That sure sounds exciting but we won't believe it until we see it. Until that happens we'll miss the ChevronWP7 jailbreak tool.
