What is the best way to backup iphone to get more space?

I can't update this iphone so I need to remove 3.6GB of photos and 3.2GB of music.

I don't use icloud… Should i?
Maybe place the phone into the computer and use itunes to backup and remove?

Rather than using a "cloud" storage (skydrive, icloud, google drive), use your PC its the most reliable and quickest way to import and export!

Using a program called itools 2013 (free) you can easily do lots of things with your device including backing up, adding, and restoring pictures
