How to Sync E-mail Accounts with Your iPhone 4S
You can sync account settings for your e-mail accounts in the Sync Mail Accounts section of the Info pane of your iPhone 4S. You can synchronize all your e-mail accounts (if you have more than one) or individual accounts, as shown in the following figure. Just select the appropriate check boxes.
The iPhone syncs with the following mail programs:
PC: Microsoft Outlook 2003, 2007, or 2010
Mac and PC: Gmail and Yahoo! Mail
E-mail account settings are synchronized only one way: from your computer to your iPhone. If you make changes to any e-mail account settings on your iPhone, the changes will not be synchronized back to the e-mail account on your computer. This is actually a good thing.
By the way, the password for your e-mail account may or may not be saved on your computer. If you sync an e-mail account and the iPhone asks for a password when you send or receive mail, do this: On the Home screen, tap Settings, Mail, Contacts, Calendars. Tap your e-mail account’s name, and then type your password in the appropriate field.
Ringtones, music, podcasts, iTunes U courses, books, and video (but not photos) are synced in only one direction: from your computer to your iPhone. If you delete any of these items on your iPhone, they are not deleted from your computer when you sync. If you purchase or download items directly to your iPhone using the iTunes app or App Store app, those items are synced back to your computer when your iPhone syncs. And if you delete anything you’ve purchased — movies, songs, TV shows, or whatever — you can download them to your iPhone at no charge with the iTunes or App Store app’s Purchased section.
