I get emails with .wmv files attached. At home on my PowerBook, I can view them using Windows Media Player. On my iPhone, nothing. I just downloaded "Flip4Mac" and am now able to open wmv files with QuickTime on my PowerBook. It works very well. Back to the iPhone... if you shoot a video and email it, the attachment is a .MOV and it will open with QuickTime on a Mac. On the iPhone, it has the QT logo, and you can play the video. So why can't they offer something like Flip4Mac as an iPhone app? It's annoying to have to wait til I get home to view wmv files on my laptop. And since wmv is such a popular format, why can't the App Store just go with the flow? If anyone knows of a way to view wmv files attached in email on the iPhone, I would love to hear about it! Thanks.
