Thanks for posting, I went to my FB account and diabled that option. Now none of my friends numbers are available to anyone but me. I don't have my on phone number listed in my profile. This is an easy fix so don't panic.

good thing I never used facebook sharet

Got rid of my cell phone. Never go into Facebook. I would be one who can unknowingly get into trouble!

I'm sorry to tell you this, but I can't use my phone to Facebook, and all my friends numbers were there, which I quickly and completely deleted! Please check and do this for your friends. They will love you for it. The notice below will help you get rid of the problem, and you can copy and paste it to your Facebook to let your friends do the same.
************************************************** *******
ALL THE PHONE NUMBERS of your contacts are now on facebook! go to the top right of the screen, click on ACCOUNT, click on EDIT FRIENDS, left side of screen and click CONTACTS. you will see all phone numbers from your cell phone (FB friends or not) are published that you have stored in your mobile phone. TO REMOVE, go to the right column, click on "this page." please repost this on your status, so your friends can remove their numbers and thus prevent abuse if they do not want them published

I tried it but those were not any of my numbers in my phone.

I went to the site and read it. For your friends numbers to be on Facebook, either:

a) you uploaded them from your phone
b) your friends shared them to you

Allegedly, no one can see the numbers but you. I'm not a FB fanatic, so will have to check that, too.

I do agree that this bears watching - especially if you have kids who have Facebook accounts.

that is scary stuff

I DON'T use FB on my phone. My phone doesn't have any fancy features and I had several phone numbers on my account!

WOWZER! Scary! Thanks for the alert!

I have an old old phone and cannot access FB or anything from it. I just checked and yes....my friends phone numbers are listed on FB under my account as the original poster of this thread said. I was not too happy to see them either as some I had no idea of their phone numbers!!! THank You for bringing this to our attention! I really appreciate it.
