I messed up and started downloading a video to my phone from the iTunes app. The problem is that I don't have enough memory to let it finish and then delete it. It won't let me swipe/delete in the meantime. Strangely enough I can get to the end of the video if I play it, the download finally disappears but then pops up again about 5 seconds later.
folks here might be able to help if you gave enough detail. Is this an email, a message, certain site, what?
