Recently i watch a Security Flaw with the iPhone running the Firmware version 2.0.2 that gave a personal access to your email account and contacts when you have your iPhone locked.

How to do this hack

  1. Go to the unlock screen
  2. Try to unlock your keypad
  3. Their will be a popup screen with a password screen
  4. Hit your home tab buttons two times and bingo, you are done

How to fix this

  1. Go to Setting> General >Home Button
  2. Double hit your home button
  3. Change your Home to Ipod , temporally fix your problem

This is a quick but not permanent fix to this security Flaw
