Microsoft has finally released the official iPhone app of the world’s largest instant-messaging network (Windows Live Messenger) right for your iPhone and iPod touch. It features all the standard Windows Live stuff like photo sharing, chat and social stream from Windows Live Home.

Microsoft is set to bring the largest instant-messaging network to the iPhone platform. Neowin has grabbed exclusive screenshots of an early build of Windows Live Messenger for iPhone, which will be released in June as part of Windows Live Wave 4 launch.
