jailbreaker means different things depending on the device that you're busy hacking preinstalled walls from. If you're fiddling with consoles, a legal team would come highly recommended, but if you're tweaking mobile code, at least Windows Phone mobile code, you're in for a much sweeter ride. The ChevronWP7 guys that brought us the first jailbreak of Microsoft's Windows Phone 7 are currently in Redmond having a sitdown and a frank exchange of views with WP7 dev experience director Brandon Watson, and the amicable nature of their discourse has been evidenced by the image above. Microsoft is clearly taking a light-hearted and community-friendly approach to handling the (now inevitable) efforts at disabling limitations to its software and we can only congratulate its mobile team for doing so.
Update: Looks like Microsoft's softie approach really is working. Shortly after the jolly news, notorious hacker Geohot announced on his website that he's going to treat himself to a WP7 device; but before long, Redmond's already reached out to offer him a free handset.
