We’ve gotten reports from customers that are currently synchronizing Daylite with Address Book and MobileMe are getting duplicate contacts when migrating from MobileMe to iCloud.
We’re asking that you hold off on migrating from MobileMe to iCloud (which we know is very tempting) until we have a workaround to prevent these duplicates.
We have a hunch on how we can prevent this, but we haven’t been able to test it as Apple’s servers are currently overloaded.
We didn’t have access to this feature during the developer betas.
We’ll update you on this situation by end of day Friday.
