I would prefer if Yappari left the contacts as they are. It's not the responsibility of a third-party app to fix your broken contacts. If I ever catch Yappari or any other application "fixing" anything of my contacts I'll immediately purge it and be angry about it. After all, your problem requires a one-off solution. Write a script for that! I seriously doubt that. Particularly at this stage of *early* development, the less people who play around with the code the less chances that one of them fvcks up. Cheers.
