When you are at the iPod Touch desktop select Settings. In the top section, right under where you select and connect to a Wi-Fi network, select Fetch New Data. Right there before you even select you should see what type of setting this is on. The default is Push, so expect to see that. When you select Fetch New Data you will be taken to the data settings. Here you can put Push On or Off, which is what pushes the new data on your iPod Touch. If you turn it off then you will have to set a Fetch schedule, which will schedule in when information is going to be pushed on you. You can set for every fifteen minutes, thirty minutes, hour, or to do it manually. Most people that are going to set to Fetch are going to do manual. The reason is that if you are just going to have data fetched every so often there is no reason to turn data Push off.
