How can I sync with this uncompatible iTunes 11.x

How can I sync an iPad Air (iOS7) and iPhone 3G with a MacBook?

To help answering this awful question:

- iTunes 11.x does not allow iPhone 3G iOS 6.x to sync.

(iPhone 3G even 3GS is not subject to iOS7)

- iPad (iOS7) does not sync iTunes 10.x

All-in-all, iTunes 11.x is a garbage!
