I rented a movie and actually was able to watch it, but in iTunes it still shows up as a download in progress with an error and when I tap the icon it just says I don't have enough memory to continue the download (for the movie that I already watched and the rental time expired for). It is taking up a bunch of space and I want it gone! Please help. I do not have a computer I can get onto at this time and don't want to lose my 100+songs currently stored on my iPhone.
