I have MobileMe myself, and on July 12th, the day after the iPhone launch, Apple got their act together and started to make their servers work again. Since then, MobileMe has worked fine for me, and quite quickly too. I had to develop a simple iWeb page and upload it to my personal iDisk, and it was much faster than .Mac.
They are working on it. They've added on a free month for many users who experienced problems, and you know they are trying to fix it. Again, I was a .Mac subscriber before as well, and my email stopped working during the transition itself. That's normal. MobileMe seems to be one of those things that "works when it works". And it works well for many.
My advice is to be patient. You should expect MobileMe to start working soon. If not, then you really should complain at Apple. Good luck.
Apple finally acknowledges the issue to the "One Percent Club," http://support.apple.com/kb/TS1953
I barely stumbled on the small link at the bottom of my account page. Unfortunately, Apple's Status History site indicates the opposite, indicating that the those in the One Percent Club have been restored. This is unnccessarily misleading and confusing. See report:
This is my SEVENTH day without mail, I lost it sometime last Thursday. iMagine my surprise when I entered a court proceeding on Monday and learned that my attorney had not received any of the documents that I had sent him. I was i-Screwed!
But now that I now know that THEY know, I can end my useless attempts to reach a Chat person. Other than MobileMe's daytime chat hours, there is no other contact option for support, other than Apple's User Forums. They turned of support contact via email days ago, and AppleCare won't even talk about MobileMe! However, now that Apple has made this brief acknowledgment, maybe this will free up some of the Chat folks to work with others on issues that they might even = be able to assist with.
The good news is that Apple DOES review the User Forums. How do I know, you ask? - they Disabled my Account ID, "For security reasons," they said. My thinking is that they had heard all that they needed, or perhaps they felt that YOU had heard all that you needed? I have not heard from Apple as to what they feel is was a "Security" reason. Maybe I still will? I'm sure that all rumors that Apple may be Censoring these forums are just rumors.
Perhaps they're right with their perceived silence strategy after all? Time can aid in healing. Now that I have been without my years-old .mac account for about a week now, I have been able to get comfortably established elsewhere - and it won't cost me a hundred bucks a year! If I can only get my lost email, and that which I never received, I would be a happy camper, even happier when if I can resolve one last detail - a refund.
MobileMe - Communications like you never iMagined!
