One of my favorite things we built in Wave 4 of Windows Live is now available. You can now download Windows Live for the iPhone, iPod Touch and iPad from the US app store. You can also get it from the France, UK and Canadian app stores. The app kicks serious butt and I use it every day.
The official spiel is as follows
Windows Live Messenger for iPhone and iPod Touch is the best way to connect with the people that matter most and keep up with the things they are doing across the web. Use your iPhone to instant message your friends list, view and comment on your friends’ photos and status updates from Windows Live, Facebook, and MySpace, and at a glance, see what your Messenger friends are sharing from Flickr, YouTube, and many other social and photo sharing sites. Make sure to visit http://profile.live.com/Services today and setup Windows Live to bring in your social networks. Messenger is simply the best way to connect with your closest friends.
Instant message with your Windows Live Messenger and Y! Messenger contacts on the go so you’re always connected to the people that matter most. You can even receive IM notifications when your app is closed so you never miss a message.
Windows Live Messenger gives you one place to view the updates your Messenger friends are sharing from social networks like Facebook, Flickr, MySpace and more, helping you cut through the clutter on the go.
Upload photos right from your phone to share your favorite moments with the people that matter most. Create albums, add captions, and let your friends and family comment on your photos.
Access your Hotmail account without leaving the app to read, reply to, and compose emails. Get email notifications within the application so you know when you have new messages.
For me, push notifications when I get new IMs is the killer feature. I used to think IM was dead on smartphones until I used this app and realized that the problem was really lack of an IM client with push notifications. If you use Windows Live Messenger, you need to cop this app today. If you need further convincing here are some pretty pictures
