Your iPhone is not bulletproof: Researchers say a newly discovered bug means the phone has a serious vulnerability to hostile wifi networks. According to Skycure Ltd., hackers can force IOS systems onto wireless networks, and then crash programs or even the whole operating system—creating what they call a "no-IOS zone." The Tel Aviv-based company says it's not sure that the vulnerability has been exploited, and adds that the new IOS upgrade fixes some of the issues it discovered.
