Requirements:


iExplorer (free) for both PC and Mac
You do not need a jailbroken device to do this


Steps:


Plug your iPod/iPhone/iPad into your computer. You don't need to let it sync
Open iExplore and let it load
Open the directory labeled "Downloads" (On jailbroken devices that should be "/var/mobile/Media/Downloads")

Close iExplore and reboot your device
