A proof of concept program has been developed that can successfully download and crack any application from the Windows Phone 7 Marketplace, according to a WPCentral report.
A "white hat" developer has provided WPCentral with a proof-of-concept program that can successfully pull any application from the Marketplace, remove the security and deploy to an unlocked Windows Phone with literally a push of a button. Alternatively, you could just saved the cracked XAP file to your hard drive. Neither the app nor the methodology is public, and it will NOT be released (please don't ask). It is important to note that this was all done within six hours by one developer.
