I've just uploaded my application 'Love letters' to market.
My intention was creating an application for Valentine's Day which allows you send Valentine cards to your friends. No internet connection is needed if you just send MMS.
Also application allows to share picure and congratulation to your friends via our favourite app like FaceBook, twitter, flickr. You can also set images as wallpaper.
I'll appreciate all suggestions and comments. If you have any issues or found a bug - please let me know.
