Another iOS 7 lockscreen bypass lets you make calls anywhere in the world for free. The flaw involves telling the lockscreen you want to make an emergency call, which is a option that cant be turned off. You use the emergency call screen merely to get the option to dial, but no emergency call is made. An earlier iOS lockscreen hole involved actally placing emergency calls and then hanging up, hopefully before they went through. We strongly urged you not to try that exploit, even on your own device, as we considered it a rotten, and likely illegal, thing to do.”]
