Thanks it is helpful. I am gonna try that out. I think we need to have .csv file exactly matches with the contacts fields we have in our mobile phone (home,mobile,genaral,fax,email,etc). Then if we import .csv file it should work. Difficuit part for me is to create .csv file since i don't have contact list any more, only the .nbu (backup) file. I'll export that and try to create .csv file and see. Thanks for the clues.
