The MobileMe Gallery app (which I previously covered back in February here) allows you to check on your MobileMe photo galleries using a beautiful user interface with a couple of neat features up its sleeve. Apple just updated the app to include a native iPad version (the app is now universal, and of course free), full iOS 4 fast app switching support, Retina Display graphics.
You can also view your friends’ galleries without the need of having a MobileMe account, which is pretty cool. The app is free and available here, check out the screenshots below.
