The iPod Software 1.3 Update provides iTunes 4 support, including playback of AAC encoded audio files (Mac-only). For Windows users, iPod Software 1.3 adds support for Audible.com content. Additional enhancements include audio playback and user interface improvements, increased playback time on scroll-wheel iPods, and longer stand-by time for all iPods.
iPod Software Update 1.3 is only compatible with touch-wheel and scroll-wheel iPods without a dock connector. The recently introduced iPods (April 28, 2003) do not need this update.
