I realised a couple of days ago that, in the iTunes iOS 6 app on the iPhone 4, you can't cancel a download once its started downloading. There was a free Sherlock episode as part of the 12 days, and I wanted to download the SD version as the HD version was huge (2.5GB). But I accidently started downloading the gigantic HD version, and I couldn't cancel. I swiped from left to right on the download. No delete button appeared. I pulled down, looking for an edit button. There wasn't one. I couldn't find any way to cancel it, so I had to wait several hours and immediately delete it. Did I miss something? Is there a way to cancel a download in the iPhone version of iTunes? Or is it just a crazy design choice by Apple?
