Shoot it! is a very cool app for the iPhone that will enable you to send a real, photo postcard from anywhere to anyone in the world directly from your iPhone. Your personalized postcard will be delivered in just days…not weeks. Easy. Just take a photo (or choose one from yor library) write the text, putt the address and they will print it and send it as a real post card.
It will cost you 99 cents for the US, $1.25 for the UK and $1.50 for Western Europe. This is what you would pay to buy and send it, but it is much cooler ;)
