Yeah its really odd. I never provided my cell phone number to facebook. And I never will. Guess I just lose the account.

Tried all of that and no soap. I am on cable and do have a dynamic ip. I am stumped. Long shot. Maybe it is my mvps host file blocking something? Or spywareblaster, adblock plus? I use all 3. Then again. I tried with IE9 and nothing. I think someone at FB has done something to my account for some uknown reason.
In that case (since nobody here seems to be having the phone number problem), my guess would be that perhaps someone had been repeatedly trying to log in with your credentials, and FB is truly using that as a pseudo security measure in an attempt to verify your identity. However, unless they already have your cell phone number on file (and they do seem to asking for a mobile phone number), I can't see how they can really use that to identify you, especially since they say they won't call you. I wonder if they have agreements with all cell phone service providers to get access to their customer records? Come to think of it, such a deal between FB and cell phone service providers would not surprise me, especially considering that FB access is a major app and selling point for newer cell phones.
In a similar vein, not too long ago my wife got internet access to her checking account locked because she forgot that she had recently changed her password, and tried using her old password too many times. In order to get the bank to reset her password, she had to call in from her cell phone (it was listed on her account as her primary phone number), and the support tech used the caller ID as one of the security checks. She initially tried calling from one of our VoIP lines, but she was told that she would either have to use her cell phone, or physically go to a branch bank and provide visual proof of identity.
