I have downloaded this free app and backing up my contacts to both VZ clouds and ITunes when I sink up. The service and the apps are free and it will maintain your contacts for 30 days. In case of ITunes issues I have a second option for backing up ! You would need to disable your WIFI during the transfer and turn back on. Depend upon the number of your contacts this process should only take minutes.
I am not sure too many people are aware of this free service.
