It may not occur to you but have you ever though about backing up data from your Facebook account?
Recently for some odd reason Facebook has decided to go Battlestar Glitchtastica on some of my friends recently to the point of having some of my friends completely lose their Facebook account information and start over. Crazy Right?
For the people who has lost all their friends Contacts, Wall Posts and even precious Photos, everyone pretty much said the same thing..They all wished they would of backed up their account somehow.
