How to sync your iPhone 4 with iTunes

When you first receive your new iPhone 4, Apple requires that you use iTunes to activate the device. Syncing your iPhone's content with iTunes is completely optional, however.
There are many benefits to syncing your iPhone 4 data with iTunes, not the least of which is ensuring that all of your Contacts, Calendars, Email settings, Web page Bookmarks, Notes, Ringtones, Music, Photos and Videos, Podcasts, Books and Audio Books are backed up. This way, if something goes wrong and you lose data on your iPhone, a quick restore is all you need to recover your files.

To set-up syncing between your iPhone 4 and iTunes, follow these simple steps:

1. Connect the iPhone 4 to your PC and launch iTunes
2. Select iPhone Option in the iTunes sidebar
3. Now, select which things you’d like to have synced – so, music, email and contacts for example
4. Once you’ve done this, click Apply – it’s in the bottom right corner of iTunes
5. Wait for Syncing to complete

That's it!
We recommend that you sync your iPhone 4 with iTunes at least once a week. In the unfortunate event that data on your iPhone is lost, this will ensure that you have a recent backup file to restore with.
