Gameloft is now producing games that are downloaded into itunes "free," but are actually lite versions that you are asked to upgrade within a device as you play it. If I download a game like Sacred Odyssey: Rights of Ayden into my ipad and upgrade it in the ipad, what will happen if I sync my iphone or my wife's ipad with itunes? Will the full game sync with different devices or will I need to upgrade with each device?
