How to save data from iphone

So i'm getting my phone fixed! And the store said to save everything on your phone to computer itunes. But i don't know how to.

Set up iCloud account and save the data. It will keep your phone's data backed up in the cloud.

In fact, once you've put the songs or video on iPod or iPhone, you can get them out of iPod or iPhone and put them on computer. You can transfer them to computer with iPod transfer. Like this one: http://welcometojenelleshouse.xanga.com/766907341/ipodiphoneipad-to-computer-transfer-review/
