Our friends at TidBITS again let us know how to keep things going well. Some of the information there is still not completely settled, but it looks like it will allow us to use MobileMe Mail and iCal syncing after the deadline.
They point out that this Apple this page says to go to me.com/move to keep using your email after June 30th.
See the MoibleMe email article here: http://tidbits.com/article/13002
They also link to another article that may allow you to use iCal http://tidbits.com/article/12669
As usual, read the comments on these article to get further info. Also let people here know what you think.
