It works!

This app works great - but you need to initialize it after downloading. Once I downloaded it, I closed all open apps. I opened this app by itself. Then I closed it. This seems to initialize it in the iPhone. It worked after that. I went into my email and opened a Word doc out of the attached winmail.dat file. This app works as advertised. I have iOS 5.xx and iPhone 4.
