The iPhone phone application allows you to make calls over your mobile network. In addition to containing the Contacts application, and being able to make a call from a Conact listing, you can also press the keypad button at the bottom of the screen to bring up a traditional phone keypad.

One nice thing about the iPhone phone keypad is you have a backspace button, so you don’t need to start all over again if you make a mistake in entering a number.
You can also enter a phone number in the keypad, and then press the + button at the lower left to simply create a contact for the number you’ve entered.
Once you place a call, you will get a set of buttons: Mute, Keypad, Speaker, Add Call, Hold and Contacts. The Hold, Mute and Speaker buttons do as you would expect. The Keypad allows you to enter in touch-tones if you are calling an automated system. Add Call allows you to call someone else and create a conference call. The Contacts button lets you view and edit contacts while talking.

The Recents button at the bottom of the Phone application allows you to see and redial phone numbers you have recently called or have called you.

is there a way to turn on “auto complete” so I don’t have to retype my email address and other form field data?
Also, how do I delete specific “recent calls”? It seems the only option is to clear all. Does it save a certain number of calls? Or are calls saved a specific number of days/hours?
sabrina: I don’t think there are command for those things. We’ll just have to wait for Apple to add them.
I am trying to do some freelancing work, but I do not want to publish my personal phone number provided by ATT to avoid unwanted calls. Is there an app that will allow me to create/provide a number apart from my iphone number so I can publish that number and not worry about unwanted call (telemarketers, prank callers)
Darshan: That’s not something an app can do. It really isn’t a solution that can be done by AT&T or your iPhone. What you probably want to do is get a business phone number through a service that allows you to redirect the call to anywhere. Lots of companies do this — voicemail, forwarding, etc. Google’s Grand Central is perfect, but they are closed to new users right now. But you can find other services.
the keypad cannot press how i can i make a call i can’t get thru pressing numbers
ehbe: Sounds like a problem. I’d bring it in or call support.

You should do a Restore using iTunes to reset your iPhone completely. Another option is to take it into the Apple Store to have them take a look at it.
