Apple's new iPod touch isn't capable of making phone calls, though if you hit up the "More Features" section of the device's product page, you might be led to believe otherwise. Why? Because Apple sucks at Photoshop.
That seems to be the most reasonable explanation as to why promotional images of the fourth-gen iPod touch show a phone function in the lower left corner, just like the iPhone. Furthermore, Apple replaced the iPod icon with a Music icon in the new iPod touch, though the promo shots show otherwise.
What most likely happened is someone at Apple got lazy and Photochopped a pic of an iPhone screen onto an iPod touch body, thus qualifying Apple for another ticket on the Fail Boat, right behind Microsoft's Photoshop team.
Well that was fast. A refresh of the product page shows someone at Apple knows how to wield a Photoshop brush, after all.
