Apple has set up a special MobileMe Mail Dedicated Chat Support to help those folks who had email issues sort everything out. If you were one of the chosen few, head on over there to discuss what happened with a friendly, and helpful, Apple support tech.
In addition to resolving the email issue, David G. says that nasty syncing issue (you remember, the one that was wiping people's iPhones of any and all contacts) has been corrected as well. Most MobileMe users didn't see this issue, and for the few that did it seems to have sorted itself out, however, if you're still having this issue check out Apple's KB article for the solution to your syncing woes.
Hey, David G., since it looks like you have MobileMe under control can I report a bug about the MobileMe Status blog? Thanks! There is no way to link directly to a post, like the post I'm talking about right this second, which makes it hard to make sure people see the entry I'm talking about. I'm sure you just forgot to click a button in iWeb or something.
