Jailbreak Windows Phone 7 With ChevronWP7
That didn’t take long eh? Windows Phone 7 has already been jailbroken, thanks to a tool called ChevronWP7 which is now available for download. Let the third part apps pour in developers!

It’s quite odd why the tool is called “Windows Phone 7 Unlocker”, since it just gives you root access to your device and does not function as a carrier unlock. But the fun part is, you can now side-load apps on your shiny new Windows Phone 7 device without having to be dependent on the Marketplace only, and also keep in mind that Microsoft doesn’t want you to do this. Thankfully the process of jailbreaking your Windows Phone 7 device is reversible. You can download ChevronWP7 unlocker from this link [Mirror 1, Mirror 2] and give it a shot on your device.
