icloudWhen introduced its iCloud wireless data sync service Monday, many subscribers were left scratching their heads, wondering what it would all mean for them.

Here are some of the facts—and, where answers don't yet exist, educated guesses—you should know as a current MobileMe member.

  • If you're a MobileMe user, you probably know the various parts that make up the service. will offer some of the same features as MobileMe (contact, calendar, and e-mail sync), but not all, and it will add new features, as well. And yes, that means MobileMe will cease to exist.
  • When the time comes, you'll be able to convert your MobileMe account into an iCloud account. Apple's MobileMe transition document says “When iCloud becomes available this , more details and instructions will be provided on how to make the move.” Although iCloud will be in full swing this fall (at the same time that 5 ships) existing MobileMe services will continue to work until 30, 2012.
  • If you've recently purchased a boxed update and haven't used the code yet, or have an unused code in your account, you may be eligible for a refund. Apple has posted a support doc detailing how the process works. You can also request a pro-rate refund for the remaining portion of your subscription. For everyone else, Apple has extended your MobileMe subscription until June 30, 2012—after which MobileMe becomes as extinct as and .Mac before it.
  • According to an e-mail Apple sent out on Monday, when you sign up for iCloud, you'll be able to keep your MobileMe e-mail address. In addition, everyone eligible for iCloud is now eligible for a free e-mail address ending in @me.com.
  • If you're wondering what will happen to MobileMe features such as Galleries, iDisk, Backup, Back To My Mac, and Find My iPhone, it's hard to say. When Apple talks about the future of MobileMe and iCloud, none of these features are mentioned. But as for Find My iPhone, earlier this year Apple made it free for owners of new iOS devices. Apple has recently updated Find My iPhone, so Apple clearly thinks it's still worthwhile. We certainly expect it to stick around.
