iPhone users, I hope you’re listening.
This is not a complete unlocking of the phone – instead, some sort of bug/race condition that tricks the phone into giving you access to the contacts and phone application. People have reported this working with an iPhone 5 with iOS 6.01, 6.02 and 6.1.
I can confirm this is working on an iPhone 4S with iOS 6.1.1
Update 21 Feb 2013: Confirmed still working with iOS v6.1.2 (10B146).
Update 19 Mar 2013: Fixed with iOS v6.1.3 (10B329) – After a month of publication Apple has finally fixed the issue.
What this means is that anyone with physical access to your locked phone can
- Make phone calls from your phone
- Manipulate the call history to hide their calls
- See who you have been calling and who has been calling you
- View/modify your contacts
- Listen to your voicemail messages
- Potentially change your voicemail greeting and other settings.
There is nothing you can do right now, other than be extra vigilant about leaving your phone lying about. The takeaway message here is that your iPhone’s passcode does not protect it as much as you would expect.
