If your phone is ever stolen or lost or wet or broken or misplaced, please don't create a Facebook Group about it. Get with Zyb, article here, or visit Facebook's own Phonebook.
You'll get a list of all your Friends, complete with their Landline and/or Mobile numbers (should they list them on their Profile). Awesome and easy.
