PC Free

PC Free was introduced in iOS 5. Rather then forcing the user to set up a iOS device by connecting it to a computer and syncing with iTunes, it allows you to enter an iCloud login and restore from a backup or set it up as a new device without iTunes, because the syncing is done over iCloud.

Features

 * New Welcome screen when you start using the device for the 1st time
 * iTunes/USB no longer required to activate devices
 * Ability to synch wirelessly to iTunes
 * Ability to update software directly on the device without needing to tether it to iTunes.

Supported devices

 * iPhone (3GS and later)
 * iPod Touch (3rd generation and later)
 * iPad (all generations)
