I am just using contacts, and find my iPhone. Truthfully, if find my iPhone wasn't integrated into iCloud, I would probably delete my iCloud account. I just prefer syncing to iTunes... I had one issue with iCloud...my contacts had like 2 - 3 different tabs for contacts, one for on my mac, one for icloud, and then just contacts...I disabled iCloud contacts, deleted it off my phone (which was a mistake cause I lost my contacts), re-synced to itunes, then re-enabled iCloud contacts, and one single tab...no issues since. Just curious what you are backing up and your experience with it so far?
