What's the difference between an iPod touch and an iPhone 4?

Need to know please!

They do the EXACT same thing. The only thing the iPhone has different is that you can call, use internet (not on Wi-Fi), message without Wi-FI.

Between the newest ipod touch and the iPhone 4 the only notable difference is the ability to call from the iPhone. On the new iPod touch you can facetime (video chat), use siri and text! Same as iPhone 4s, just no plain voice calling.

You can't make calls with ipod.

You can use iPhone4 to make phone calls.
