Microsoft has just released a Windows Phone SDK update for Windows Phone 7.8. It’s basically an optional update that brings two new Windows Phone 7.8 emulator images to the already existing SDK installation. This is good news for developers as the two images should enable them to fully test how their Windows Phone 7.5 app’s Live Tiles will look and behave when they are running on a device running Windows Phone 7.8.
New phones with Windows Phone 7.8 are beginning to ship, so it’s a great time to update your apps to take advantage of the new Live Tile experience and to reach the new markets that Windows Phone 7.8 makes available, Microsoft said. However, it’s worth noting that the official Windows Phone 7.8 update is still coming. In response to a question regarding the official launch, a Microsoft spokesman said, “We know you’re eager to get the Windows Phone 7.8 update, and we want you to know that we’re working closely with our hardware and carrier partners to get it tested, approved, and rolled out to as many devices as possible in early 2013.”
