Securicodes allows you to hide applications, delete contacts or the entire message library through a simple unlock

  Securicodes is a tweak released during this day in Cydia, and with its help you can undertake a variety of actions by simply entering an unlock code for your iDevice. The tweak allows you to set security codes that unlock your iDevice, but at the same time automatically delete all SMS or history of web pages accessed through Safari, allow you to hide applications, delete bookmarks from Safari, plus many others. The tweak allows you to set codes that perform the respective functions even without actually unlocking the iDevice, so you can protect yourself against anyone very simply and easily.

Have you ever given your phone to someone to play around with, hoping that the person wouldn't go in and check your SMS or browsing history? Now you can discreetly delete or hide information just by entering a code on your default lock screen. Securicodes extends the function of the passcode lock screen by allowing you to associate certain actions with certain custom passwords. For example, you can associate a password with deleting your SMS's upon unlocking, and then another for deleting your Safari history.

You can also set custom passcodes to the same as your default passcode to execute an action every time you unlock the device. Alternatively, you can set passcodes that don't even unlock the device, instead just executing the action. You can either use numeric passcodes (like "1234") or full passwords. You can delete SMS's, contacts, browsing history, hide or launch an app, wipe your device, and more!

  The functionality of Securicodes is not limited to the previously mentioned functions, because with its help you can: delete the entire list of contacts, delete everything you have in your iDevice, open an application from Springboard, perform a respring or reset, plus many others. Securicodes has a dedicated menu in the iOS Settings application and there you can associate your codes with the various actions you want to take. Securicodes is available for $1.99 in Cydia's BigBoss repo.
