If you think the proximity sensor on your iPhone 4 has been acting wacky, don't worry, turns out you're not crazy: Apple has just committed to fixing weirdness in the next software update at its press conference today. Problems have mainly revolved around the sensor failing to detect your face when you're on a call, leading to accidentally hang-ups, mutes, and so on as your ear makes contact with the screen -- not too cool. Then again, if you've been staying off your phone lately for fear of dropping a call, well... maybe you didn't notice.
