Would still like to have an easy way of editing my contacts though. Brought them over from my old sim and the names are messed up and numbers missing etc. I thought there might have been a way to do it on my PC, but not looked for anything yet.
Export to csv, edit, delete all contacts on your pc (try a few first of course so you have confidence) than import back. That's what I did to get rid of the dup and triplicates that google sync caused on my blackberry.
The same could be done with outlook if you have contacts there. Outlook is one of the prime targets of viruses so I would avoid using it if possible though! Good luck!
