An Apple spokesperson has confirmed to Boing Boing Gadgets that the upcoming iPod Touch does not include Bluetooth, despite rumors to the contrary today. An image had made the rounds earlier today—the corner with the purported Bluetooth icon in the corner is reproduced here—but Apple has said it is not an official image.
While there wouldn't have been much use for monophonic Bluetooth headsets in the iPod Touch, the lack of Bluetooth precludes the possibility of wireless Bluetooth stereo headsets or microphones that could be used with a future third-party VoIP application.
Update: Some eagle-eyed readers have pointed out that there are Bluetooth icons on images on the Apple.com pages. (See this post's comments.) Since Apple roundly denies there is Bluetooth in the Touch, I think we can chalk it up to a Photoshop blunder. (Once they hit the street and someone tears it apart, we'll know for certain if there's Bluetooth hardware in there or not.)
