My MobileMe account expired last week. I just logged in to see the status of my account and as expected, Calendar, Gallery, and iDisk are all blacked out an not accessible, with find my Phone still enabled. But oddly enough, the contacts still function as normal. Either this is a result of my account being in purgatory for the moment, or contact syncing is part of/will be part of MobileMe for free. That's my take anyway.
