Birthdays is very simple application that allows you to keep track of upcoming birthdays on your iPhone.

In order for this application to actually work, you will need to add (or have) Birthdays assigned to your Contacts, obviously. To add a Birthday to a contact….go to your Phone app, select Contacts, select a contact, tap Edit is the upper right corner, scroll down and tap on Add Field, scroll down and tap Birthday, enter the date of the person’s Birthday and tap Save in the upper right corner.

When you open the Birthdays application, you will see the main screen in which it displays birthdays in the current month, next month and then any other birthdays. The list will display the contacts name and the day and the month of their birthday. If you tap one of the people in the list, you will be able to see that person’s contact info.

The app is currently in beta, but it works well and illustrates how useful even simple apps can be, and points up the everyday utility of the iPhone. It’s available in Cydia and is free for download for those of you that have a jailbroken iPhone.
