The iOS 4 has a major security problem and we have reported this a couple of times now, one letting you know about the flaw and again letting you know that it can potentially block people on your contacts list calling you.
Well now Apple seems to be on top of things and will give it a quick fix, the security flaw allowed you to bypass the iPhone password protection without using a jailbreak or hack that could simply be done with a few actions.
Hopefully in the next few weeks a fix will be added within the release of iOS 4.2, Apple is aware of the problem and will offer a fix as part of the iOS 4.2 software update in November.
Hey Jailbreakers, have you got a fix yet? Please let us know if you have tried the password bypass and if so what happened.
