I was having fits with Verizon's back up assistance, deleted contacts and double contacts as well. I found a fix that worked for me. I deleted all of my commando contacts, also deleted my google contacts from gmail. I made sure my contacts on Verizon were the way I wanted them, they were updated to my phone within minutes. I turned off the automatic back up assistance and turn it back on only when putting in new entries, the new entries are only entered on the Verizon site. Once transfered to the phone the back up turned off. I used a program called " Free Opener " and converted the contacts to a cvs file and uploaded them back into google gmail, for a second backup.
