A newly-published teardown of the third-generation iPod touch by iFixit has revealed that the player contains an 802.11n-capable Wi-Fi chip, despite being listed as an 802.11b/g only device. According to the article, the iPod touch 3G sports a Broadcom BCM4329FKUBG wireless chip, which the manufacturer states is n-compatible.
Notably, this chip appears to be more advanced than the 802.11 a/b/g-only Broadcom BCM4325 chip found in the iPhone 3GS, and also offers support for Bluetooth 2.1 +EDR and an FM receiver and transmitter. In addition, iFixit found enough space left at the top of the board—6mm x 6mm x 3mm—to house the video camera found in the fifth-generation iPod nano, but not enough to fit a more robust sensor like that found in the iPhone 3GS.
Finally, the iPod touch’s ARM processor is labeled 339S0075 ARM, possibly indicating a later version of the processor found in the iPhone 3GS, which is labeled 339S0073 ARM.
