Here's an awkward oversight by Microsoft's Windows Live Messenger. You have an ad for the Live Messenger app for the iPhone and it lists all the platforms Messenger will reach out to.
You have the iPhone, Android devices, Blackberry devices and the PC. Wait... what's missing?
We all make editing blunders but to forget your own mobile platform? Microsoft is gaining momentum with Windows Phone and really should be missing any opportunities for exposure. Especially when they are advertising their own services.
