cb radio box on iPhone4

[lbtwhn]

after updating ios and iTunes, cb radio box app no longer works on my iPhone. i tap the icon, the g&g logo appears, the progress bar goes to 100%, the app comes up for exactly one second and then i'm back to my backdrop. i have confirmed with apple that my phone is working properly, both hardware and software. of the 100+ apps i have installed, cb radio box is the only one that isn't working properly since the ios and iTune upgrades. is anyone else having this problem? how to fix?
