Dies kündigte Microsoft in einer Rundmail an:
After December 31, 2014, no Windows Phone 7.x unlock capabilities will be available. This means, for those of you who have not unlocked your Windows Phone 7.x device, testing of apps directly from Visual Studio on that device will no longer be possible. However, app testing can still be done on other unlocked phones, or via the Windows Phone Emulator, or by submitting beta apps through the Windows Dev Center.
