Hi, I don't know what has happened but after an occasion of updating my ipod touch, some applications logo in the ipod touch became greyed out and says "waiting.." in the title. It can't be tapped, deleted, or ran in the ipod touch and doesn't have anything related in the itunes as well. As you can see in the photo its just a block of grey now but it used to have the greyed out logo of the app before. When I as an experiment deleted the associated app, it became a greyout block. Does anyone else haev this problem?
