Enthusiastic developers who've been holding back from registering with Microsoft's WP7 developer program by shelling out $99 have a reason to rejoice. The ChevronWP7 community has developed a solution that allows users to unlock their WP7 phones for just $9. This enables them to test and try the apps without having to first signup with Microsoft for the same purpose. Now, that's a very good alternative. In bold terms, it's just like jailbreaking is to iOS but then it's legal and by Microsoft itself.
For the uninitiated, this will allows users to load third-party apps for WP7 legally on their WP7 devices.
