justWink – This cool app for the iPhone and Android lets you send customized greeting cards using your mobile. Add your personal touch with your own words rather than a tacky, ready-made phrase. Throw in a photo from your phone, and an actual signature to show you care. Choose from a variety of e-card themes including birthday, thank you, baby, wedding, friendship, even just because. Once you’re done you can send the greeting card via Facebook or email.

justWink’s interface is super easy to use, and it only takes a few taps to send your customized greeting card. See for yourself with this iPhone screenshot:
