One of my friends lost their cellphone and she can't find it anywhere, she said she doesn't know what could have happened to it. She said the last time she had it was on the bus on the way home from school, she thinks maybe someone took it, she checked everywhere on the bus, and she checked in the book bag, purse, anywhere where she could have put it. I was wondering if there is some type of tracking thing I could do online, that you don't have to pay for, or download, if there isn't, what else should she do?
