MobileMe has officially closed it’s doors for iCloud, but you can still download all of your data.
If you head over to MobileMe.com you will find a a closed sign (above) – when you first open the page it moves a little bit the side, like a door closing. If you haven’t already moved to iCloud, this site will allow you to. You can also download your documents and photos using the links.
It appears that you can also initiate a “Find my iPhone” search straight from the page.
