“This is my password,” said the King as he drew his sword. “The light is dawning, the lie broken.” (C.S Lewis)
The establishment of a password on your iPhone is a wise move. It is an easy means by which to ensure your data security. Even emails and attachments will be effectively encrypted and protected by this simple system.
Unfortunately, there is a loophole.
This issue concerns users who set their iPhone password using iOS3 and have since upgraded to iOS4. In this circumstance, data encryption may fail.
How to confirm if your password is secure?
Step 1 : Settings > General > Passcode Lock
Step 2 : Enter your passcode to reveal the Passcode lock screen and scroll to the bottom of that screen.
Step 3 : Find the confirmation ‘data protection is enabled’ in dark blue letters.
If data protection is not enabled, perform the following steps.
Step 1 : Disable your passcode in Settings > General > Passcode Lock
Step 2 : Back up your device. Connect it to your computer. Go to iTunes, Control-click and select Back Up.
Step 3 : Restore your device by clicking the Restore button in the Summary screen in iTunes.
Step 4 : Enable your passcode again, which turns on encryption.
