Need some Help Finding Bugs / Beta Testing in Lil Racerz

I need some help with some Beta testing and bug bashing!

I have a game on the app store that when it works gets glowing reviews, but it seems to crash on different phones.

Its a top down car racing game… Lilracerz from here:

itunes.apple.com/au/app/lilracerz-pro-rally/id372283058?mt=8

I am basically looking for people to download it, then if it crashes on your phone to become a part of my beta program by sending me your UDID and I can send you one or two updates to help nail the problem.

If you have the time to help out, I have 30 promo codes below, please let me know what code was used and if it works / ( try restarting a level a couple of times ) or fails. If it fails please can you send me your UDID so I can send updated versions.

Thanks for the assistance,
