Suddenly I went to favorites and realize most of my phones have no names only phone numbers. I went to all contacts and they are not there. I lost names addresses and all info. I need to know if is still there? in the memory? or I need to do it all over again.
Try importing your contact list from Verizon Backup Assist.
If you do not have that, then upload them from your saved contacts in your computer.
If you do not have that, then try to restore your backed up phone data from a previous backup on itunes.
If you still have none of those, then yeah. You're SOL and will have to manually insert everything. I recommend afterwards getting the backup assist app and backing everything up so you don't have to do that ever again.
Hope this helps!
