After install, I loaded the app. For a split second I saw something about connecting to the network, then the intro video started. But after about a second the screen went black. I pressed the Home button to quit.
I then started the programme again, no intro video. I started mining but this time I couldn't move any of the pieces.
I deleted, reinstalled, and exactly the same thing happened with the intro video. The game was playing OK however.
I tried deleting, turning off, and reinstalling one more time, and exactly the same thing happened with the intro scene. I have a 16GB 3G iphone (and no clue how to get the crash logs)
When I updated (had 5 go through at once) I was having the same issue with ALL the updated programs. I don't really thing the crashing is AF's fault, probably faulty apple code. I turned it off completely, turned it back on , and it worked fine. I did have something weird happen when it did work though. The screen went black, but i touched the screen and the video controls came up and I was able to hit play (somehow it had gotten paused). After that everything worked wonderfully. Love the tools, love everything about the update!!! I still get stuck 'bigger' blocks though.
I had a problem when first opened, then reopened and was ok. Although had a crash during one of the blueprint sessions - got stuck in a loop of sound and screen freezed. I had to turn off iphone, and restart.
