I am trying to sync the app "Pages" onto my iPhone 4s. I connect to my computer and sync. The app on my phone shows the app is installing. The progress bar makes it look as if the app is installed, but then it goes back to being an empty bar. I cannot click to open it and there is no "x" on the left hand side to delete or quit. Any suggestions? I have tried resetting as well. Nothing works. I can't delete the app and I can't get it to upload.
