Windows Phone 8.1 update for Sprint HTC 8XT to be available on December

If you are a Windows Phone developer and test your applications on a Windows Phone 8 devices, you’ll need to re-unlock your device before May 14, 2015, 2:00 GMT. Microsoft has just sent out emails to developers which revealed that the Windows Phone 8.0 certificate that validates developer unlocks is going to expire on May 14, 2015, 2:00 GMT (May 13, 2015, 7pm PDT?.)

If your device is already unlocked, you’ll need to re-unlock it to expand the time to test the device. Keep in mind that this doesn’t affect Windows Phone 8.1 devices – only Windows Phone 8.0 devices. Here’s the email that Microsoft sent to developers:

“If you have a Windows Phone 8.0 device that you use to test your apps, please read this mail.

The Windows Phone 8.0 certificate that validates developer unlocks will expire today May 13, 7pm, Pacific Daylight time.

We recommend that you re-unlock your Windows Phone 8.0 test devices prior to today 7pm, to continue testing for another 24 months.

After today, no Windows Phone 8.0 device will be able to be developer unlocked, and you will have three options to continue testing Windows Phone 8.0 packages:

  • Update the phone to Windows Phone 8.1 and unlock it for developer testing
  • Submit apps as beta through the Windows Dev Center and test with Windows Phone 8.0 devices
  • Test Windows Phone 8.0 apps via the Windows Phone emulator

Any Windows Phone 8.0 device currently unlocked will continue to be unlocked and work as a test device until its certificate expires. To maximize the time available to test with this device, please lock then unlock the device before May 13, 2015 7pm PDT.

Note that this change has no impact on apps available in the Windows Phone Store, has no impact on Windows Phone 8.1 devices, nor will it impact customers with Windows Phone 8.x devices.

The Windows Store team”
