Oh Apple, your sneakiness knows no bounds. Last week Steve Jobs unveiled Apple’s most ambitious iPod Touch to date – front and rear facing cameras, a high res display, and support for Facetime, Apple’s mobile video chatting feature.

Previously, Facetime was supported exclusively on the iPhone, and since the iPhone is, well, a phone, being made aware of an incoming Facetime chat wasn’t a problem. The iPod Touch, however, is a somewhat different beast, so Apple shrewdly decided to include a vibrator inside the latest iteration of the iPod Touch. Essentially, when an iPod Touch user is on a wi-fi network and receives an incoming Facetime request, the device will vibrate.

Originally pointed out by iPodTouchFans, Apple’s accessibility page for the iPod Touch reads:

If somebody wants to start a video call with you, you’ll receive an invitation — along with a vibrating alert — on your iPod touch asking you to join. Simply tap Accept, and the video call begins.

Though some speculated that perhaps Apple merely copied and pasted the text from the iPhone accessibility page, the FCC teardown of the most recent iPod Touch shows clear signs of a vibrating motor. Note: the “vibrate motor” tag is user drawn and not part of the official FCC teardown.
