Apple confirms iOS 6.1 lockscreen glitch, iPhone 4S battery drain persists


Apple (NASDAQ:AAPL) has confirmed that iPhones running its iOS 6.1 are vulnerable to a security flaw enabling anyone to bypass the smartphone's lockscreen, granting them access to a number of core device functions.

The iPhone lockscreen exploit involves making and immediately canceling a call from the emergency dial screen, then hitting the power button several times to load the Phone App button. The Phone App allows anyone to access the device's dialer, contact list, voicemail box, call history, messages, photos and FaceTime.

"Apple takes user security very seriously," a spokesperson said in a statement supplied to ZDNet. "We are aware of this issue, and will deliver a fix in a future software update." Apple did not specify when the iOS 6.1 update will reach consumers.

Apple issued iOS 6.1 to iPhone, iPad and iPod touch devices two weeks ago. Some iPhone 4S owners soon began complaining the update accelerated battery drain and prompted some overheating issues, and British operator Vodafone even warned subscribers not to upgrade iPhone 4S models after determining the software triggered 3G connectivity problems.

Apple responded earlier this week with the release of iOS 6.1.1, which purported to resolve those performance and reliability concerns. But Wired notes that consumer comments across a range of forum threads indicate the battery life issues persist. "iOS 6 was seamless for my phone and I experienced no issues," one Apple forum member wrote. "When I converted to 6.1, the battery retained about 30 percent of its usual lifespan and overheats. 6.1.1 hasn't improved the situation." Another added "I can confirm that 6.1.1 didn't fix the battery drain problem. Prior to IOS 6.1 my battery would last almost 2 days with light usage.  Today with iOS 6.1.1, my battery went from 100 percent down to 26 percent in 6 hours. I only sent 2 text messages."

Apple said Wednesday it is also scrambling to address another iOS 6.1.1 bug preventing some iPhone and iPad users from syncing their mobile mailbox with Microsoft's (NASDAQ:MSFT) Exchange Server 2010.

iOS 6 users (including iOS 6.0, 6.1 and 6.1.1) now generate 83.1 percent of all iOS web traffic in North America, according to online advertising network Chitika. iOS 6.1.1 accounted for 1.4 percent of all North American iOS impressions within 24 hours of release
