I love this app - it is one of my favorite iPhone applications. I never miss a birthday now that I have it. After checking out all of the other birthday / anniversary applications, I think this one is the best, especially because although it will pull birthday information from your Contacts, it does not require that you add all of its entries into your Contacts. The push technology in version 3.0 is a great addition - it will display a pop-up reminding you of a birthday or event. Although I see some users have reported crashes, I found out that it is only because Apple has not yet approved the push service module and that once the push service module app is approved by Apple and purchased, the app will work as expected with push technology. One more thing - the support for this app is outstanding!
