One iPhone hacker said that the device from Apple Inc. is actually recording all the activities that the users do and see on their mobile handset.

According to Jonathan Zdziarski, the iPhone records screenshots of the most recent actions of the user. The device does this in order to have the fading applications effect once the user clicks the home button. Jonathan Zdziarski is the author of the upcoming book which has a lengthy title – iPhone Forensics: Recovering Evidence, Personal Data, and Corporate Assets.

The screenshots in the iPhone were presumably deleted after the user closes the application. However, it can still be recovered with the help of forensics techniques. This is like getting the data deleted in other storage devices so that it can be reconstructed for law enforcement purposes.

Jonathan Zdziarski said these details recently in a webcast. He also demonstrated on how one could access the password-protected iPhone.

According to the report from Wired.com, Jonathan Zdziarski said that there is actually no method to prevent it. He hopes that Apple Inc. can give a solution to this because it can be a way to get into one’s personal and private information. However, feeling divided, Jonathan Zdziarski also feels that it can be a useful tool for investigating law breakers.
