Q: How do I edit my e-mail contacts/address book in the iPod Mail app?
A: You should be able to find a “Contacts” app on your iPod touch. By default, this app is located in the top-right corner of your home screen, although if the home screen icons have been reorganized it may be on another screen or within another application folder.
You can also search for the app, or any of your contacts, by swiping to the right from the home screen to bring up the search screen and either entering the word “Contacts” or the name of the contact that you would like to edit.
Alternatively, you can sync contacts from a number of different desktop apps or online address books via iTunes on your computer or wirelessly via services such as MobileMe, Google Sync, or Microsoft Exchange.
