Resetting iPod touch

Reset all settings: Choose General > Reset and tap Reset All Settings.

All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.

Erase all content and settings: Connect iPod touch to your computer or a power adapter. Choose General > Reset and tap “Erase All Content and Settings.”

This resets all settings to their defaults and erases all your information and media:

ÂÂ On iPod touch 3rd generation or later: by removing the encryption key to the data (which is encrypted using 256-bit AES encryption)

ÂÂ On iPod touch 2nd generation: by overwriting the data

Important: You can’t use iPod touch while data is being overwritten. This can take up to four hours or more, depending on the model and storage capacity of your iPod touch. (On iPod touch 3rd generation or later, the encryption key is removed immediately.)

Reset network settings: Choose General > Reset and tap Reset Network Settings.

When you reset network settings, your list of previously used networks and VPN settings not installed by a configuration profile are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and “Ask to Join Networks” settings are left turned on.

To remove VPN settings installed by a configuration profile, choose Settings > General > Profile, then select the profile and tap Remove.

Reset the keyboard dictionary: Choose General > Reset and tap Reset Keyboard Dictionary.

You add words to the keyboard dictionary by rejecting words iPod touch suggests as you type. Tap a word to reject the correction and add the word to the keyboard dictionary. Resetting the keyboard dictionary erases all words you’ve added.

Reset the Home screen layout: Choose General > Reset and tap Reset Home Screen Layout.

Reset location warnings: Choose General > Reset and tap Reset Location Warnings.
