The 2nd generation of the iPod was introduced on July 17, 2002. Using the same body style as the first generation, the hold switch was redesigned, a cover was added to the FireWire port, and the mechanical wheel was replaced with a touch-sensitive wheel. The front plate also had rounded corners and edges. The second-generation class was available in 10 GB for US$399 and 20 GB for US$499. The first generation 5 GB iPod was carried over, but its price was reduced to US$299. Notably, the second-generation iPods and the updated first-generation iPod were now Windows-compatible. These versions came with a 4-pin to 6-pin FireWire adapter and were bundled with Musicmatch Jukebox. At that time iTunes was Mac only and unavailable for Windows.
