iOS7, backwards compatibility and launch images

Question

I want to submit an iOS app that is prepared to run in iOS5+ versions. It is a tabbed app, so the launch images I got for iOS6 and earlier have the default shine in the tab bar's background. However, now that I compiled the app also for iOS7, the tab bar's background has no shine. I keep the default tab bar's appearance for each iOS version, I mean, when my app is running in an iOS6- device it has the shine effect, and it has no shine when running in iOS7 (I've seen than some apps have adopted the new appearance even for iOS versions prior to 7, like Twitter app).

Since Apple's Human Interface Guidelines says that the launch image should look like your app's main view (without controls)... which launch images should I provide? iOS7-like, or iOS6-like?

Thanks

You can set different launch screens for iOS 6 and iOS 7. Take a look at this picture from Xcode 5 (Project properties page, under "Launch Images"):

Anyway, it's not an enforcement from Apple, ie., if your launch screen doesn't match the main app screen exactly, your app will not be rejected.
