Just bought the family pack for MobileMe and downloaded the app on my iPhone 4. Very disappointed that the app does not allow for file uploads to the service. Even the DropBox app lets me upload files on my iPhone, granted you only get 2GB for free, but still.....it's free and you can do it! Don't get why Apple doesn't allow iPhone file uploading to MobileMe. If they don't change this, then I probably won't renew it.
