Check this out [ame=http://www.youtube.com/watch?v=thszqGA0rMk]YouTube - Egozoo Cards for iPhone[/ame].
I'm not the developer nor I know him. It's just a video that the developer posted in another forum in which I'm member and I thought that you may like it. Hopefully, you do.
Might be this program is interesting for you:FaceUp! Greetings this app creates animated greetings. You can crop the face of your friend and paste it into any of background provided (28). Also animate face mouth and add verbal and text greeting. So you can greet with any holiday, occasion like birthday, etc. And it is free.
my favorite is hiCard Suite. I've used them since 2008 and it's $1.99 for about 200 types of cards (unlimited send). They also have hiCard Classic, which has less types of cards than the suite, but it's $.99. Sorry, can't post the link.
It creates video cards with your photos (taken with your iphone, already on your iphone or on your facebook albums) and you can add some texts. The video cards are very funny and you can send them by email or post them on facebook.
justWink is BY FAR the best card app! … especially if you dig a little off color humor. It’s a free app. You can post cards onto yours or your friend’s fb wall, send by email or text. Plus, they just added a new option which allows you to pay to send an actual card. I’ve been using this app for 6+ months and LOVE it!
