Protect My Privacy protects you against applications that transfer various types of data

  Protect My Privacy is a new tweak released for the iOS platform today that allows iDevice owners to protect themselves against applications that transfer various types of data to the developers' servers. The tweak gives us the opportunity to protect ourselves against applications that send data regarding: the UDID of our iDevice, our location and the address of contacts from our terminals. As soon as you install the tweak, it will display a notification message every time an application tries to send data and we have the option to allow or deny its access to that data.

Protect My Privacy (PMP) lets you protect your personal information on your iPhone. When an app attempts to access this information an alert is shown and you have the option to "Protect" or "Allow". When protect is chosen, PMP supplies fake replacement information, such as randomized contact names, or a location specified by you. You can quickly switch between real and fake information, even while the app is running using the Notification Center widget. You can protect your Location, Identity and Contacts (Address Book). Future versions will protect even more information types.

To enable the Notification Center plugin for iOS 5, in your Settings app, Notifications, scroll to the very bottom and you will see Protect My Privacy in the "Not in Notification Center" section. Tap it and turn it on. Then after you tap the back button, tap edit and drag it to the very top so it appears first in the list.

  In order for the respective applications to continue working without problems, Protect My Privacy provides the application with false data, either specified by us or randomly generated by the tweak. Protect my Privacy also has a widget in the Notifications Center that allows us to set fake data for applications and that can be activated from the notification center menu located in the Settings application of iOS. Protect My Privacy is available for free in Cydia in the BigBoss repo.
