Last night the suite of previously known 'Bing apps' on Windows Phone received the anticipated rebrand, bringing back the old MSN moniker instead. All the apps on Windows Phone managed to get the update, although only one Windows 8.1 app – Bing Finance – had its name changed to MSN Money. Tonight, the rest of the apps are now refreshed.
Assuming you have said Bing apps installed, if you head to Settings and check for App Updates in the Store, you will likely see all of them with pending new versions of all the apps. From MSN Weather to MSN News to MSN Health & Fitness, the apps now feature MSN instead of Bing near the top.
