You probably connected your iPhone or iPod touch to your computer when you first bought it to get your music. Have you connected it since then to synchronize it with your computer? If you haven’t, you should.
Syncing your iPhone with your computer will do three key things. It’ll update the apps, music, videos, podcasts, photos, etc. on your iPhone based on whatever you have on your computer. This may be all that you expected would happen. But, it will also backup your iPhone so that if you lose your iPhone (or replace it for any other reason) you can load the new one with a backup and get everything back as it was. It’s really seamless and will appear magical the first time you setup a new device from a backup. The other benefit syncing will give you is that iTunes will periodically check to make sure the system software on your phone is the latest and greatest version. iTunes will prompt you to download and install the newest version of the OS if your phone isn’t up-to-date. You’ll get new features and/or fixes for issues when your OS is updated.
These are three great benefits to regularly syncing your device with iTunes. Do it at least monthly. You’ll want that backup one day in the future!
