Was the MobileMe product already for sale before today? I ask because I didn't notice it before today.
sites typically don't go down during an update. i work for an ecommerce company, and when we update a site, it is all seamless to the user. servers will go down briefly, but it has nothing to do with a site update. if that was the case, espn would be down every 2 mins.
All that I knew. What I was trying to determine was if the addition of MobileMe to the Aplle Store might have been the reason for its closure. I think your answer infers it was not the reason.
