You clearly didn't get my meaning. Its an iPod 4G. Its the phone without built in calling. If you were to refer to my earlier post, you can see that using the iPod as a phone isn't difficult, and with 4G replace wifi with the 3G/4G network and you have a phone.
iPod Touches do not have 4G network access. Also, you don't have Wi-Fi everywhere you go, and even if you can detect Wi-Fi networks around you, it's highly unlikely that you'll be able to connect to them because the majority of them are either passworded or require a payment/subscription, or both. The iPod Touch 4th gen is not "an iPhone without the phone." Sure, you can call with it. Sure, you can text with it. But for one, you need apps that can call and text, such as Skype and TextFree, and secondly, you cannot do those things unless you have Wi-Fi, which is rarely available at any place besides your own home.
