You may never have seen this, in which case you have a good day now. The rest of us have turned to our iPhones and found that an app we need urgently is greyed out for no clear reason. Or a whole folder is. Or the app does say Installing and you realise it must be an update as you installed this one months ago -- but then it keeps on saying Installing. Perhaps the very worst is when it just says Waiting. Surely, there can be no worse torture inflicted on a law-abiding iOS user than having an app say Waiting, in perpetuity.
