Well today i was hanging around with my mates when we went into the canteen, and my friend wanted to see whos activated blue tooth on. Well not sure what he has done but he made the phone ring even if the phone was on silent. Although we did have a crack but in my history class with a stricked teacher, my friend thought it would be funny to pick on the goths/emos in the class so he switched their ring tones on and well they had got the phone taken of them, but i couldnt help my self laughing while people are confused when the ring tone was still going.. Does anyone know how do use this feature? cause i read on wikipedia that it isnt legal..
