With iOS 5 and iCloud i was hoping that games would get synced across devices. If I'm playing a game on my iPad and then later pick up the same game on my iPhone, then i would like to be able to start right where i left off on my other device. Are there any games that currently do this? Or is this even currently possible?
Starbase Orion was one of the first ones out that synced all local games through iCloud. There are of course many, many others, so the answer is Yes - this exist by design and developers can make use of it as long as their data fits within the storage requirements of iCloud.
Scribblenaughts Remix does this, I have played on iPad where I left off on iPhone
