Security Bug in Apple iPhones

Apple gadgets are very well known for their security. But it has been proved wrong for iPhones. Jonathan Zdziarski, a security expert exposed a security bug in apple iPhone which enables hacking of the phone to access user's private data.

Usually we set security codes in our phones so that others cannot access datas of our phone if misplaced. Zdziarski told that he can easily unlock an iphone's security code with the help of a manipulated firmware update.

He told he can also destroy the neat graphical interface of the iphone. In iPhones when we close an application, it appears as if main menu flies throughtout the screen to replace it. This is made possible with the creation of screenshots of previously viewed image. These screenshots are not deleted as soon as it completes this task, and thus can be seen by others using our phone.
