I use my iphone and Google Voice for 2 separate purposes and as such I have 2 separate contacts lists one on my iphone that is synced with my google apps account and the Google Voice that is synced with my gmail contacts. Unfortunately this applications imported all of them without asking into one list now so I had to spend half a day fixing it, however every time you launch the app it does it again. Am I missing something or is there a way to turn this off. Seems like a great application but if it is going to destroy my contact lists every time I launch it I can't really use it.
Hopefully if this isn't an option now to turn off contact syncing it is something you can add in the future, as aside from that the application seems great and something I'd definitely use over the google's web application.
