Microsoft works with modders, offers unlocked WP7 via ChevronWP7 labs

Sony and Apple, listen up. This is how you score massive street cred with developers. Microsoft has thrown its weight to support ChevronWP7, group of programmers that essentially jailbreak Windows Phone 7, allowing other users to load homebrewed applications with Microsoft’s approval. The only cost is a minimal fee via PayPal. It comes as no surprise as Microsoft has traditionally been very accommodating with hackers and modders that play with their hardware, judging from the variety of Kinect hacks in the wild. Kudos to you, Microsoft.
