I have some exciting news — the American Cancer Society, the official sponsor of birthdays, launched a new mobile application for the iPhone and iPod Touch today!

I’ve spent the last hour playing with it and now I can’t put it down! The free – yes, free! – app links up to my contact lists and Facebook so I can track my friends’ birthdays and receive alerts so I never forget to send them something on their special day.

But the app is not only practical — it’s also a ton of fun! My favorite feature is the birthday cake animation. I get to choose from different cakes, customize my own greeting and send it to my friends on their birthdays. I can even blow out the candles!

You can even make a donation to the American Cancer Society to help create a world with less cancer and more birthdays, right from your phone!

So if you have an iPhone or iPod Touch, download it for free at the iPhone App Store or watch a demonstration of the application below.

Check out the More Birthdays app today and I promise, you’ll never forget another friends’ birthday again!
