Apparently now phones can make a ringtone that's called "Mosquito", which is not audible to a lot of people over 20. According to several articles I read, kids turn this on during class so they can text message without their teachers knowing (well, most of their teachers, at least). Now, I can hear it just fine... and it hurts my ears :|. I know Katie will hear it, and probably Danielle. Can everyone else hear this?
