It's not impossible...

I came to this newsgroup to find a way to search for 'Restricted' and
'Private' cell phone numbers that had been toiling my girlfriend. I
have 3 friends that all work in the cell phone industry, ranging from
repair to programming/flashing/etc etc. Now I don't know the
intricacies of cell phone operation and such, but I do know how to use
the internet. If you're really focused on finding a number, you wont
come to a newsgroup, you'll do some in-depth searching.. Even if the
people on here did/do know how to find a number, they probably
wouldn't tell you due to legal implications. I found my answer and it
took me all of 30 minutes. It's out there and it's doesn't have to
cost you an arm and a leg, just put forth some determination. Good
luck.
