How can you make your iPod Touch back up faster?

Sorry, but the last person said that deleting apps (creating storage) makes you download faster. This is wrong. Also, doing two things on WiFi at the same time slows down other things. So if you want to download faster on you iPod, its best to stand closest to your Wi-Fi router (where the signal comes from). And if no one is using the Wi-Fi except you, then downloading the app will be much faster.
