No valid 'aps-environment' error msg only on device run...

Hy,

i run the cloud sample app in simulator, and the dashobard shows all functions. But, when i run on any device (iphone3gs, iphone4, ipad) then the dashobard shows only a dark layer, the buttons are in another position. The xCode terminal show this log:

SpringBoard[67] <Warning>: No valid ‘aps-environment’ entitlement string found for application ‘CCloud’: (null). Notifications will not be delivered.

I try to build with 1061-1085, and all version show this.

Is it any code what build.settings need, or…what should the reason of this error, and only on device?

Thanks in advance.
