Calling

While waiting for my broken mobile phone to be replaced, I decided to try to use my fourth-generation iPod touch as a mobile phone.

Apple's Visual Voicemail system not only lets callers leave you a voice message, it allows you to pick which message you want to listen to.

 You can convert phone numbers into contacts very easily with the iPhone. You can even add an additional number to an existing contact. Here's how you do it:

1. Tap on the Phone icon from your Home screen.

2. Tap on the Keypad option in the menu bar at the bottom of the screen.
3. Dial the phone number but don't tap Call.
4. Instead, tap the Add Contact icon to the left of the Call button.

It is sometimes handy to access another app while you're on a phone call. For example, you might want to look up a movie time or check a shopping list while talking to your spouse. (Note: if the app requires 3G access, this can only be done on an AT&T iPhone.) The iPhone makes this easy to do.

1. While you're on a phone conversation, tap the Speaker icon and press the Home button.
