I am trying to submit my first iOS application to AppStore using xCode 4.2.
I always get status of : "Invalid binary".
For the first time I got the following explanation:
"
iPhone 5 Optimization Requirement - Your binary is not optimized for iPhone 5. New iPhone apps and app updates submitted targeting iOS 6 and above must support the 4-inch display on iPhone 5 and must include a launch image with the -568h size modifier immediately following the portion of the launch image's filename. Launch images must be PNG files and located at the top-level of your bundle, or provided within each .lproj folder if you localize your launch images
"

but when I add the requested launch image I get another failure with following explanation:
"
Invalid Launch Image - Your app contains a launch image with a size modifier that is only supported for apps built with the iOS 6.0 SDK or later.
"
My target OS is iOS 5.
Please help
