"#geohot if you want to build cool stuff on #wp7, send me email and the team will give you a phone - let dev creativity flourish #wp7dev"

We have jailbreaking for iOS and rooting for Android to perform amazing customization, hacks and side-loading of applications which aren’t allowed in the official Marketplace due to use of restricted APIs and low-level hacks, to get the homebrew scene started on another front first ever jailbreak/unlocker for Windows Phone 7 is out now available for downloading.

Named "ChevronWP7" the simple to use utility promises to start a new era of side-loaded Windows Phone 7 development, allowing developers to not only develop on the platform without a WP7 marketplace account costing US$99/year but also make use of non-public API's pushing the boundaries to customize, tweak and hack their devices at low-level.
