Any game that has IAPs should have iCloud saving, no exceptions. This wasnt always the case, but that was because iCloud saving wasnt always there. Now it is. If you are sufficiently advanced to force stupid, inane, badly focused ads on your patrons, you are sufficiently advanced to also give them iCloud saves. It should be required by the App Store by now, especially for games that are being backed by gaming giants like EAs Chillingo.
