iPod Touch from Apple is the first iPod to include WiFi capability. Before the device was released, pictures were shown that included a Bluetooth connection icon on the top right corner of the screen next to the battery meter. Users were excited about the idea for using a Bluetooth headset to listen to music or sounds from the iPod Touch. Finally, the iPod Touch was released and a team from iFixit wanted to find out if there indeed was a Bluetooth chip inside of the device.
They took the entire iPod Touch apart and looked at each chip. Now, they have found the WiFi chip, which is a Marvell W8686B22 802.11a/b/g WiFi system-on-chip does not have Bluetooth functionality. The iPhone however, has a similar Marvell W8686B13 chip for WiFi and a CSR 41B14 BlueCore4ROM chip which provides Bluetooth.
There is still no final word on Bluetooth connectivity for the iPod Touch. There are still a few unidentified chips inside the iPod Touch labeled as Apple logosw. Maybe a future firmware update will finally end the Bluetooth mystery or it may end when Apple deicdes to release its final word on the iPod Touch. Via Engadget.
