Note: At this moment you can try to downgrade iOS 7 to iOS 6.1.3 and iOS 6.1.4 because signing window for this firmwares is still open. But hurry up because it will be closed soon. Otherwise downgrading process will be possible only on iPhone 4 and only with saved iOS 6.1.3 and lower SHSH blobs. Step 1. Download iOS 6.1.3 for iPhone 4, 4S, iPad and iOS 6.1.4 for iPhone 5S.

If iTunes doesn't allow you to complete this process that means that Apples closed signing window. In this case you can downgrade iOS 7 on iPhone 4 and only if you have SHSH blobs for that.
