Last night, I did nothing out of the ordinary.
This morning, I woke up to all my contacts, favorites, and call log history GONE. My Droid Incredible isn't synced to my Gmail account, meaning I unfortunately don't have a backup for my contacts. However, my contacts were connected with Facebook and Twitter. I received a "Facebook authentication" error message but fixed it simply by re-entering my password. Twitter was not working last night, but it is working fine now. All my texts are still on my phone, but with no matching contact, so there's no picture or name to go along with my texts.
This is all the information I can give. I don't know what happened.
I don't want to go through all the trouble and time to add contacts all over again if there is a simpler solution. If there's no hope, then it's my last option.
Anyone know how I can possibly retrieve all my contacts back? Thanks in advance!
