How can I delete a paused application download on my iPhone? I started installing an application from the App Store but forgot to check its size. When I check now, it is 50 MB. Now I don't want to download that application any more because I'm on 3G plan which is costly. I paused it but don't know how to delete it. Can anyone help me on how to delete a paused app download?
If you can't delete the paused download (which, I'm thinking, suggests you aren't on the most recent release of iOS), then the simplest option that doesn't require a restore is going to be to find a WiFi hotspot and let the app finish downloading. Personally, I'd go that route (especially if out-and-about or on vacation, etc.) before wiping my data and having to restore again.

Alternatively, leave it on paused until you get home to your primary network. Your phone doesn't care two cents about your paused app downloads, so it shouldn't get in the way of anything.
