iCloud saves?

Ok, can someone explain how exactly these are supposed to work because they don’t seem to do what I expect. Infinity Blade 2 and Civ Rev for instance have icloud support. If I manage my data files I can see the save listed there but all I can do is delete it. On my ipad and iphone the saves do not seem to be recognized from one device to the other. So IB2 has a unique save on each. Civ I only have the one save, and I can’t load it on the ipad. So what gives?

I noticed that with Civ Rev, too. The cloud save is squirrelly, sometimes not showing up on one device or the other (iPhone/iPad). When it works it’s awesome, but I think the save doesn’t always make it to the server.
