How many of you have a mobile me account with an @me.com email address that syncs mail, contacts, calendar, etc. As well you may have an @mac.com e-mail address or other that you use for your iTunes account. iCloud only recognizes one Apple ID. To my knowledge there is no way to combine accounts, so were all stuck. I think the only choice is to pick between which is important to you, keeping all your music under your iTunes account and using that as you iCloud ID, or going with your e-mail, calendar, contacts ID that you get from MobileMe. Big Conundrum!!
