iFixit网站iPod Touch就对其进行了拆解，但在这个周末，他们又进行了补充，主要深入研究了iPod Touch的网络功能，主要目的是证实iPod Touch是否彻底删除了蓝芽功能模块。

下图中右边的小块PCB连接了背后的WiFi天线。

这里，出现了iPod Touch的WiFi芯片，Marvell W8686B22，尽管苹果宣称iPod Touch仅支持802.11 b/g，但实际上这块芯片的规格还支持802.11a。类似的，iPhone的WiFi芯片为Marvell W8686B13，但同时拥有一颗CSR 41B14 BlueCore4ROM芯片提供WiFi功能。由于iPod Touch的PCB上还有多块标着苹果Logo的未知功能芯片，因此至今还不能证明iPod Touch究竟有没有彻底删除蓝牙模块。
