To download an app on your iPhone, you simply need to click the "Buy" or "Install" button on the appropriate page, but what do you do when you start downloading an app by mistake or you find that the download is taking more time than you’re willing to invest? Fortunately, you can stop the transfer and remove the partially-downloaded program from your phone once and for all.
Tap the icon of the app you want to stop downloading. This will change the status from "Downloading" to "Paused." If you want to resume your download later, just tap the icon again.
Plug your iPhone into your computer using the provided USB cable. If you want to remove the partially-downloaded app permanently from you iPhone, you will need to use iTunes, as the phone itself will not permit you to remove downloads in progress.
Open iTunes if the program does not open automatically.
Click the "iPhone" icon in the left column. You will then see your iPhone’s system information in the main window.
Click the "Applications" tab.
Delete the partially-downloaded app from the list in the iTunes window.
Click the "Sync" button in the bottom right corner of the window. Your iPhone will update with all of the apps visible in iTunes, eliminating the one you have just deleted.
