A newly discovered security flaw in iOS 4.1 allows you to bypass the Passcode lock on a jailbroken/non-jailbroken iPhone. This’s pretty serious as someone who bypasses your Passcode can cause serious damage through long distance calling and your contacts are wide open.
Here’s how the exploit works:
- On the Passcode screen, go to emergency call.
- Dial a fake number. I dialed #1337.
- The moment you see the red “end call” bar press the sleep/wake button. You’ll need to perfect the 1-2 combo.
- You’ll then be taken to the phone app, with full access to calling and contacts. You can share contacts and that’ll launch Mail. Mail contacts exposed too.
