Your organization can also purchase App Store app licenses that they assign to you for a period
of time, but that the organization retains. You’ll be invited to participate in your organization’s
program in order to access these apps. After you’re enrolled with your iTunes account, you’re
prompted to install these apps as they’re assigned to you. You can also find them in your
Purchased list in the App Store. An app you receive this way is removed if the organization
assigns it to someone else.
Your organization might also develop custom apps that aren’t in the App Store. You’ll install
them from a webpage or, if your organization uses mobile device management, you’ll receive a
notification asking you to install them over the air. These apps belong to your organization, and
they may be removed or stop working if you delete a configuration profile or dissociate iPhone
from the mobile device management server.
