Microsoft will block ChevronWP7 unlock with first Windows Phone 7 update

Microsoft is planning to block the ChevronWP7 unlocker with its first Windows Phone 7 update due shortly.

Members of the ChevronWP7 confirmed the block in a blog posting on Wednesday. “Although this has been subtly communicated before, we’d like to reiterate Microsoft has informed us the “coding error” used in the ChevronWP7 unlocker will no longer work after the next Windows Phone 7 update (officially announced at CES 2011),” wrote the ChevronWP7 team.

ChevronWP7 famously released their Windows Phone 7 “unlock” tool in late Novermber that allowed owners to side load home-brew applications. The tool, named ChevronWP7, used a method to trick the OS into registering itself as a Windows Phone 7 developer device with the application rather than Microsoft directly. Microsoft normally charges $99 a year for the privilege of loading developer applications. ChevronWP7 pulled the tool at Microsoft’s request just two weeks after it was originally released. It was later revealed that Windows Phone 7 devices “phone home” after around two weeks to re-lock unofficial developer devices, rendering the tool useless.

Chevron’s developers – Rafael Rivera, Chris Walsh and Long Zheng all agreed to remove the tool and engage in discussions around officially facilitating homebrew development on Windows Phone 7. Microsoft is flying the team out to Redmond next week to begin the official discussions to allow homebrew application development on Windows Phone 7. The ChevronWP7 confirmed their meeting with Microsoft in a blog posting on Wednesday. “In addition to our homebrew focus, we will also be pushing for stronger protection of WP7 developer intellectual property (IP) on the platform as we believe both can co-exist on the platform,” wrote a spokesperson.

WinRumors recently interviewed Greg Sullivan, Windows Phone 7 group product manager at Microsoft, at CES 2011. Sullivan confirmed the ChevronWP7 meet and revealed that the software giant would have more to say about homebrew on Windows Phone 7 in the coming months.

Update: Microsoft’s Brandon Watson has confirmed that ChevronWP7 will no longer function in future. “Yes, the hole ChervonWP7 team found is closed,” wrote Watson in a tweet earlier today.

  • Tired of the BS

    Microsoft took a huge leap backwords with this OS… so pathetic and sad. Why does every manufacturer act like they can control what you do with your own items? I bought the phone, I pay for the service… what’s the problem? So, I’m guessing next is a laptop that can’t sideload others’ applications, only authorized Microsoft BS. Get out of the control game and you might get your name back in the race… You are almost 4th in the race for the best phones now. WM6.5 beats wp7 any day in my opinion.
