Recommended iPhone App - Greetings

I just downloaded the Greetings application to my iPod Touch and I have to say that I'm impressed.

Greetings allows you to browse over a dozen categories such as: Birthday, Friends, Miss You, Love, Get Well Soon etc, and get cute cards that you can share with anyone, anytime. Found something that you like? Attach a voice message, or photo to your greeting and send it over email or SMS at no cost to you. You can also publish greeting cards directly to your Twitter account.

Also, you can receive notifications when your friends has viewed or replied to your greeting, by email or SMS.

Download here or directly from your iTunes store (search for: Greetings)
