Is there a way to sync iCloud data with a Nokia phone? I am using iCloud but I also have a Nokia phone that I use for emergencies. Apparently it has a calendar and an address book built-in.

Is there a way, using some software to sync the Nokia phone with iCloud via PC or mac?
The only way to sync a non-Apple device with iCloud is to sync your Mac with iCloud, then sync you may with the device using iSync.
