The facebook contacts matching ability in iOS 6 is quite good, however, there are still cases when matching does not work (typical scenario: you're FB friends don't use their real name exactly...). Therefore you have to manually match you're iCloud contacts with you're FB contacts. That works pretty well - but it seems that these manually matchings of iCloud/FB contacts do not sync with other iOS devices. Thus i have to match duplicate iCloud/FB contacts on each of my device instead of doing it only once. Do you have the same problem? And if, any solutions yet? Thanks!
