How to transfer data from an iPhone 5 to an iPhone 4?

I have an iPhone 4 that I need for certain purposes and I would like to transfer my data off of my iPhone 5 to the iPhone 4. Does anyone know how to do this? Google doesn't seem to have any answers.

Backup the 5
Restore from that backup on the 4
Using iTunes.

Back up your iPhone 5 with iTunes or iCloud, then restore your iPhone 4 from the backup. But you should know this will replace the data on your iPhone 4. Another option is using an device-to-device data transferring tool, AnyTrans, which allows you to transfer data from iPhone to iPhone without erasing any data.
