Microsoft has released an official version of Windows Live Messenger for iOS devices. Windows Live Messenger allows iPhone and iPod touch users to chat with their Windows Live Messenger and Y! Messenger contacts and view updates from social networks such as Facebook, Flickr and MySpace.
Push Notifications are supported for new IM notifications. Users can also upload photos directly from their device and create albums, add captions and allow friends and family to comment on photos.
Windows Live Messenger also provides built-in support for Hotmail so users can read, reply to and compose e-mails and receive e-mail notifications within the application. Windows Live Messenger is available from the App Store as a free download.
