iFixit has told Gizmodo that it is possible that the Bluetooth chip has been hidden somewhere in the internals of the iPod touch: “We’re looking into it. It’s hard to say because they can disguise bluetooth antenna on the PCB and the chip could be integrated into something else. I’ll see what I can dig up.”

Apparently Gizmodo (and most other people) assumed that iFixits lack of report on Bluetooth implied that there was no Bluetooth, however it seems they were mistaken. “We’re talking more to iFixit on the matter. There was a faulty consensus that their lack of report on Bluetooth implied that there was no Bluetooth. That was our mistake.”

According to Engadget, Broadcom, Marvell, and CSR all offer single-chip solutions with combined WiFi and Bluetooth radios, and they have heard from a decent source that the internals of the iPod touch are very similar to that of the iphone and that there is a Bluetooth chip in there — it’s just not activated.
