I feel like this answer is here somewhere, but I've never seen a reason why. Why do no games, at least that I'm aware of, let you import/export your saved data? There are apps that let you do this, just not games that I'm aware of. I like to play around with my stuff, jailbreaking, beta firmwares, etc. What I don't like is losing my progress after getting to level 89 of whatever game I've been playing. I like how Road Trip, as an example, let's me export my data by email, then if I decide to setup my iPhone as a new device and not from backup I can easily get my data back.
