ChevronWP7 may have gotten the axe, but that doesn’t mean unofficial jailbreaking of Windows Phone 7 is a thing of the past.  According WinRumors, developer Julien Schapman is working on a new tool that will allow users to access now-restricted aspects of the Microsoft OS.

“My unlock method is similar to that of ChevronWP7 in the way they both use a fake registration server, but my method is different and more reliable… For example it automatically detects when a WP7 is plugged in and will check if this is a registered developer phone, if not it will register it once and for all, so the device will never re-lock like with ChevronWP7.”

Included tools in the Unofficial Windows Phone 7 Device Manager will allow users to manage and manually install applications, add ringtones, backup data locally, and browse the file system.

Schapman says the tool will be released following Microsoft’s first major update to their new mobile OS, which is due in February.
