Installing apps on your iPhone with iTunes could be a burden as it requires you to use the elusive iTunes sync. iCloud on the other hand, does not allow the installation of separate iPhone apps but rather the restore of the entire iPhone to a previous state.
This is a quick tutorial showing you how to install individual apps and app-related data such as preferences and documents without iTunes, iCloud and without the need to jailbreak.
