Let the great Windows Phone 7 unlocking begin! ChevronWP7, the Microsoft-sanctioned Windows Phone unlocker, went live today. The project is aimed at "hobbyist developers," giving owners of WP7 handsets the ability to run and test unsigned apps on their phones. Interested parties need a Windows Live ID and $9 to sign up -- that price'll give you unlimited unlocks on a single phone. You can grab more info and an unlock token at the source link below.
