I have a me.com address that works on my iPad and on my Mac.
However, I am trying to set up iCloud to sync all of my devices on my Mac using the instructions found here, http://www.apple.com/icloud/setup/mac.html
When I get to the second part of step 2 and check the Mail radio-box, I get a pop-up asking me to create an iCloud email address. I enter my me.com address and get this message, "This email address is already taken. Try picking a new one."
Am I supposed to create a SECOND me.com address for iCloud? Should my current me.com address work? Won't 2 addresses just confuse things further? What can I do to troubleshoot?
A side-note. Last night I successfully migrated data from gmail to my me.com calendar and address book. Everything worked successfully on my Mac but I cannot see any of the updates on my iPad. I want these updates on my Mac to push onto my iPad and I wonder if this issue is creating the problem. Everything seems to be working on the individual devices just not on the Cloud.
