There’s a special app for the Apple iPhone especially for those Valentine lovers which lets the iPhoner blow a kiss properly. The application is called “Blow a Kiss” and is available from the Apple iTunes App Sore for free.
Once Blow a Kiss is launched the iPhoner types in their name and then the recipient’s along with their email address and short love message, and then you simple blow into the iPhone’s screen.
Blow a Kiss for the iPhone identifies the kissing sound and shoots off the email to whoever you chose. When the recipient receives the email it’s adorned with hearts and shows the message in a lovers pink theme.
