I was able to fix the problem
I had the same issue with not being able to see the dice, but I was able to fix the problem. I deleted the app off my phone and rebooted it, then hooked my phone up to my computer and updated my phone to 3.1. I then went into iTunes and then went to applications. I clicked on lock n roll 2 and deleted it. I rebooted my computer and then reloaded lock n roll 2, then reloaded it thru iTunes from my computer, on to my phone. I then tried the game and it worked perfectly, so if anyone is having this issue, follow these instructions, and it should fix the problem.
