The fantastic folks from iFixithave got their hands on a brand new, hot out of the factory 3rd gen iPod touch. So what do they do with it? Tear it apart!
So, what did they discover? Well, two interesting things.
First, the 3rd gen iPod touch is home to a Broadcom BCM4329FKUBG wireless chip. According to the Broadcom spec sheet, this chip supports 802.11n.
There also a Bluetooth 2.1 + EDR and a FM receiver and transmitter packed into that chip
What's extra interesting is that not even the iPhone 3GS has support for 802.11n.
There also seems to be room in the iPod touch for an iPod nano style camera.
By now you should know how we'll get 802.11n support ... at some point in the future Apple will release an update, but because it'll be "adding a new feature" it'll claim that we have to pay $10 for the update, even though primarily it'll consist of bug fixes, minor improvements and more integration with the iTunes Store. It sucks, but its the way it is.
