14-year-old Grant Thompson was getting ready to play video games with his friends when he stumbled upon an alarming glitch in Apple's Facetime feature.<br /><br />That confusion turned out to be a major bug in Apple's group FaceTime software which allowed iPhone users to hear audio from the recipient's phone even if that person had not yet picked up the call.<br /><br />Apple says it is aware of the problem and will issue a software patch later this week to fix the bug.<br /><br />Until then, users are being told to disable FaceTime until the fix is made.
