I've had the Droid X for about a month now.. I was able to sync my contacts for the first week with backup assistant. I tried to back up my contacts again with B.U.A. but it wouldnt do anything. I called verizon and told them the situation.
Apparently you have to UPDATE your contacts on GMAIL or any synced email account to your phone. Verizons still to this day having issues with B.u.a.
I have to use GMAIL for my contacts. It'll still attempt to connect to backup, but it fails everytime. It only says 14 are synced out of 200.
HOPE THIS HELPS FOR EVERYONE WITH A DROID HAVING ISSUES!!!!
