Windows Phone 7 days have come in their full glory and so have the limitations of the WP7 Marketplace. For some folks who prefer freedom, now there is ChevronWP7, an unlocker that promises to “unleash the potential of your Windows Phone 7”, or simply put – allows your WP7 phone to get experimental apps that have not passed official Marketplace approval.
Sounds like Cydia's reincarnation for Windows Phone 7, but we are yet to see if it gets as popular as the iPhone's unofficial app store. However, it looks user-friendly and informs you kindly that “the unlocking process does not modify or damage your phone's operating system in any way and can be easily reversed”. Last but not least, the company is underlining that unlocking has nothing to do with piracy. So if you feel like you need to let your WP7 phone breathe free, try out the app at the source link below.
