The iPod Touch is equipped with Wi-Fi 802.11b/g. All iPod Touch models have included the applications Music, Videos, and Photos (collectively duplicating the standard functions of the iPod Classic), iTunes (providing access to the Wi-Fi Music Store), Safari, YouTube, Calendar, Contacts, Clock, Calculator, and Settings. Later models added Mail (accessing POP/IMAP/SMTP e-mail), Maps, Stocks, Notes, and Weather, which could also be added to the earlier models with the purchase of a US$20 software upgrade. Direct links to web sites can be added to the home screen by the user (called "Web Clips").
