I'm running on iOS 5. I've got the game installed on my iPhone 3GS, iPad, and my wife's iPad 2. No matter which version I use, when I try to launch the map or HUD tutorial video, the game crashes.
Now, I certainly have complaints about how crappy iOS 5 runs on older-gen Apple devices, but I don't feel like that's the issue here since I tried it on an iPad 2 with no success.
What's the deal, FFG?
