Do you know that you can now share your purchase/downloaded apps or music, videos with your other iDevices which are sharing the same iTunes account with you? Yes it's already possible. First make sure that you login to all your iDevices with the same iTunes account, now go to settings> store/ on each one of your iDevices and turn on features you want to share, books, apps, or musics. Next time you download an app on your iPhone, the app will automatically be downloaded into your other devices as well.
