Here is another iPhone App for which I actually paid money. The app is somewhat free, since you pay for the service using it: sending physical postcards by mail. The idea is that you would make a picture with the iPhone, and then transfer it to the Shoot It service for printing and mailing (appstore). They support many countries, including US and Europe. This is a fun way to reach someone who is not an email addict... The costs are high: $0.99 for the US, and $1.49 for Europe except UK ($1.24). One free card is included, hence the app costs are compensated. They actually print and send EU cards from UK, and therefore it takes a while to reach the destination. It took a week for Germany. The quality of the print is fine.
