There are reports around the internet today that MobileMe—Apple's paid-for membership to heaps of Mac/iOS4 services—has been blocked in Saudi Arabia. As you know, the Saudi Arabian government has had a hot temper in the last year when it comes to technology, specifically products (like BlackBerry smartphones) and services which are too secure, and keep their data on foreign servers.
Various commenters on 9to5Mac have found that the block is pretty ad-hoc with MobileMe users, dependant on whether "https" or "http" is used in the URL.
