Configuration profiles define settings for using iPad with corporate or shcool networks or accounts. You might be asked to install a configuration profile that was sent to you in an email, or one that is downloaded from a webpage. iPad asks for your permission to install the profile, and displays information about what it contains, when you open the file. You can see the profiles you have installed in Settings > Genera; > Profiles. If you delete a profile, all of the settings, apps and data associated with the profile are also deleted.
