Abeg, why dem include 30 pin dock connector? Based on di question wey dey above, write one context wey go contain di answer. E fit be 1 - 20 sentences. Context: <response>: The third generation start to include 30-pin dock connector wey allow for FireWire or USB connectivity. Dis one make am better for compatibility with non-Apple machines, as most of dem no get FireWire ports dat time. Later, Apple begin dey ship iPods with USB cables instead of FireWire, even though FireWire still dey available separately. As we reach first-generation iPod Nano and fifth-generation iPod Classic, Apple stop to use FireWire for data transfer (but still allow for use of FireWire to charge the device) to reduce cost and form factor. As we reach second-generation iPod Touch and fourth-generation iPod Nano, dem don remove FireWire charging ability. The second-, third-, and fourth-generation iPod Shuffle dey use one single 3.5 mm minijack phone connector wey dey act as both headphone jack and data port for the dock.
