| |  |  | I am not happy about this.  I realize the Win Phone 7 platform is dated at this point, but this will cause bad feelings among developers, myself included.  This is not how MS should be acting:      |          |  |              | Windows Phone       Developer, 
 Starting December 31, 2014, it will no longer be possible to unlock       Windows Phone 7.x devices for app testing. We recommend that you  unlock your Windows Phone 7.x devices prior to       December 31, 2014 to continue testing with those devices for another 24       month.
 
 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.
 
 Please note that this change will not impact apps available in the       Windows Phone Store, nor will it impact customers with Windows Phone 7.x       devices. Additionally, if you have apps that only have a Windows Phone       7.x package, now is a good time to  update these apps to Windows Phone 8 or 8.1.
