iPod Touch v2 Secretly Has Bluetooth, But Will Apple Enable It?In their teardown of the iPod touch version 2, iFixit found a secret surprise: A Broadcom Bluetooth chipset! Though totally unannounced and not listed on the spec page (Apple says Nike+ doesn't use Bluetooth), the iPod touch's Bluetooth chipset supports 2.1+EDR. We don't know for sure yet if it has A2DP, which would let you use stereo headphones—and be another hardware one-up over the iPhone besides ">the built-in Nike+ functions. We've got our fingers crossed—what else would it be used for? Update: MacRumors notes that Nike+ uses the same 2.4GHz frequency as Bluetooth, so that might be what's going on here. [iFixit]
