Passcode Lock Flaw Allows Unauthorized Access to iPhone
Other

A new security flaw has been discovered in recently released software update iOS 6.1, which allows anyone (thieves?) to bypass the passcode lock on an iPhone. This means that anyone can easily view or modify contacts, check the voicemail, send text messages, make FaceTime calls and even access photos (by trying to add a photo to a contact) even when the iPhone was locked. A wireless carrier had warned users not to update to iOS 6.1 as those who did found themselves unable to make or take calls, send texts and browse the Internet. Apple recently sent iOS 6.1.1 to repair the issue that could impact cellular performance and reliability for iPhone 4S. The new iOS 6.1 bug involves holding down the power button and aborting an emergency call.

What Else You Need To Know

  • As the glitch involves using the emergency calling feature, it's likely that iPads and iPod touches are not susceptible.
  • Another bug with iOS 6.1 relates to Microsoft's Exchange ActiveSync for push email, calendars, and contacts, which glitch is causing servers to slow down.
  • Apple has been recently embroiled in a series of software snafus, highlighted by problematic mapping software launched together with iOS 6 in September.
