MobileMe Gallery App Available For iPhone, iPod touch
From Apple:
The new MobileMe Gallery app is a great way to view the photos and movies in your MobileMe gallery right on your iPhone or iPod touch. You can browse your photos with simple tap, flick, and pinch gestures, and even view your friends’ albums, no matter where you are. And the MobileMe Gallery app automatically stores photos after you view them so you can quickly access them again, even without a network connection.
The MobileMe Gallery app for iPhone and iPod touch is available free through the App Store here.
