I was sitting in a public place yesterday when my phone asked for my passcode twice. I remember my phone asking me for a passcode when I tried to transfer multimedia files from my mom's phone to mine. That time, my phone was in idle mode. Does that mean someone attempted to connect with my phone without my permission or a key had been keyed in by accident?
How far does a phone have to be from another phone to connect by bluetooth?
How much information can be transferred by bluetooth? Can SMS and phonebook entries be transferred as well?
I heard people can get your phone number by bluetooth. Is this true?
