One of our favorite applications on the iPhone is, go figure, the phone! It’s an extremely simple but well-done app. One of the hidden features of the iPhones phone application, that hasn’t been mentioned anywhere else yet, is it’s advanced Caller ID which we dubbed “Super Caller ID.”

After placing or receiving a call on the iPhone you can go into the phone applications recent calls menu and select an individual call and be brought to a menu like the one seen below.

iPhone Caller ID

Notice anything interesting? Directly underneath the phone number there’s a line giving you the area where the phone number’s located! In this example, the phone number displayed is a Nextel cell phone from the Ventura, CA area, and the iPhone came back with the number being from the “Northern Los Angeles Area.” We also did a few other tests and the iPhone was extremely accurate with cell phone and landline numbers from around the New York Metro area.

It’s a shame that the iPhone doesn’t automatically display this information on incoming calls. We’re sure we’re not the only ones who get calls from numbers in area codes that we’re not familiar with. The iPhones super Caller ID feature could be a big help to a lot of people and a major selling point of the phone for many consumers. Alltel recently introduced a similar enhanced Caller ID service, called City ID, available only on certain handsets with an additional monthly fee. Our guess is that the iPhone has a built in database for this super Caller ID function, because it wouldn’t make sense to constantly retrieve this information over EDGE. So why hasn’t Apple boasted about this super Caller ID feature anywhere yet? We love it.
