Time is running out! Apple will discontinue MobileMe services at the end of June, 2012. If you’re using MobileMe, you have until June 30th to migrate your mail, contacts, and calendars to iCloud. You’ll also need to pull your iDisk files and gallery photos off MobileMe. Here’s a useful FAQ about the transition.
MacMaven Consulting can perform the migration for you if you’re not comfortable doing it on your own.
