there are 1 million different possibilities before getting the right number. And I don't know about you guys, but I get more than enough wrong numbers for me to worry about 1/100000 people getting my number.
Yes, there are a huge number of possibilities if you don't know where to start, however, DanggxAmanda has stupidly posted her location on a public forum. With that information, it is easy to determine the area code. There are only a certain number of prefixes assigned to cell phones in that area. It's really not that difficult from there.
Normal people aren't going to look that up. Predators are everywhere, even on MacRumors. This child has gone WAAAAY too far revealing her personal information. She posted her photo, her school, her car, her license plate, her BFF photos, the fact the she giggles about her '69', she repeats that she is a "teenager", she likes her sexy phone, she lies to her parents about where she is going, etc.
She is a little Tease with no knowledge about the real world. She is going to get herself in trouble if she keeps revealing so much private information to the perverts out there.
I believe that she has placed herself in a dangerous situation and continues to add fuel to the fire. Go back and read through her posts. Google her screen name and see what pops up about her. See if you agree.
