i got an error "App cannot be installed as its resources have been modified" while installing the iphone app in my device.. What is the reason for this and how can i fix this? my device has iOS 4.3.3 and build is 4.2 is it problem?

It just happened to me also. I just updated the iTunes and then again it was giving error then I restarted it and it's working fine.
