Restrictions or Parental Controls can be a very useful feature within iOS 5. This feature enables you to customize what exactly is allowed on an iDevice. Restrictions can be used as a type of Parental Controls. This includes enabling and disabling iTunes, App Ratings, Safari, YouTube, and more. This allows parents or others to setup an iPod or iPhone with the satisfaction of knowing certain things are off limit. With Restrictions you can also setup password frequency to prevent your iTunes password from being stored for any amount of time.
Mainly this feature is useful for parents who wish to protect their children from accessing certain features on their iPod or iPhone, but there are also many other logical uses for Restrictions.
Thanks again guys!
