It appears an unlocking tool for Windows Phone 7 devices will finally meet its end with the release of the first update to Microsoft's mobile platform.

ChevronWP7, the first and only attempt thus far at unlocking Windows Phone 7 devices had a bright but short official life when it was released in November last year, before being scrapped by its development team after less than a week. At that time, Microsoft enthusiasts Rafael Rivera, Chris Walsh and Long Zheng said they had been contacted by Microsoft, who were interested in establishing a working relationship with the trio.

Not content with that answer, the wider Windows Phone enthusiast community wasted little time in bypassing blocks in place to prevent use of the tool and for a time it appeared a lively, if small, homebrew scene would be allowed to persist.
