Looks like Apple’s latest version of iOS is riddled with bugs. The latest is related to the lockscreen, which on iOS 6.1 can be easily bypassed with some button mashing. The source of this exploit is a YouTube video, which demonstrates how to get past the lockscreen on an iPhone running iOS 6.1, giving access to the Phone App.
The process of keystrokes looks completely random, which suggests that it was discovered by accident. It involves opening the emergency call screen from the lockscreen, followed by bringing up the ‘slide to turn off’ screen and immediately cancelling it. The next step involves making an emergency call and ending the call immediately. Next the iPhone needs to be put into standby, followed by bringing the lockscreen back on. This time the power button needs to be held down again for about 3 seconds and while still holding it the emergency screen needs to be brought back up again. With the power button still held down the Phone App comes up, at which point the home button should be pressed, which will result in a screen snapshot if done properly.
While the process is not complex it sure is tricky because it requires timing to be perfect for it to work. Access to the Phone App by default also grants access to contacts, which leads voice mails, SMS, photos, email and even FaceTime.
MS Exchange Sync bug
Apple has formally announced in its support page that it has found a patch for the bug in iOS 6.1 which causes excessive communication between the phone and Microsoft Exchange servers during syncing. This results in excessive network usage and reduced battery life.
Apple has identified a fix and will make it available in an upcoming software update. In the meantime, you can avoid this bug by not responding to an exception to a recurring event on your iOS device. If you do experience the symptoms described above, disable then reenable the Exchange calendar on your iOS device using the steps below.
- Go to Settings > Mail, Contacts, Calendars
- Select the Exchange account from your Accounts list.
- Turn the switch for Calendars to OFF.
- Wait ten seconds.
- Turn the switch for Calendars back to ON.
