Microsoft is pushing out a round of updates to its Bing apps for Windows Phone that takes away the Bing. But only from the titles. So Bing Weather becomes Weather, Bing News becomes News, Bing Sport becomes Sport. You get the idea. So, if you accepted an update and suddenly wondered why your 'B' app category was somewhat thin on the ground, this is why.
You can still find them all in the store by searching for Bing, so at least you don't have to wade through endless weather and news apps to find what you want. And to find them on your phone just scroll a little further. Other than that it's pretty much business as usual!
