Apple's iOS 7.1 update appears to have killed the most useful bug ever to grace a mobile operating system



From TUAW:

Nested folders -- or folders-within-folders -- were a long-standing bug that Apple conveniently ignored for some time. It was a fantastic hidden feature that I've personally become dependent on. Having a perfectly clean home screen with a single folder used to house all my different app categories was a dream come true, but reality has now smacked me in the face.

  Warning: Dont upgrade to iOS 7.1 if you like your nested folders
