WindowBreak, which was recently released, offers users and developers a wider variety of apps and a much-needed boost to accomplish a more efficent jailbroken system that actually works. Developers have recently tested WindowBreak on Windows Phones with some very impressive results.
In this past year many developers have attemped to jailbreak Microsoft's Windows Phone 7, but were only able to access a few features. ChevronWP7 was the first crew of developers to create this jailbreaking concept for the Windows Phone 7 OS. After some encouragement from Microsoft, developers have come up with a tool designed to perform a full jailbreak on the Windows Phone 7 OS.
