While setting up my iPhone 4s I was setting up the icloud email. I had an inactive dotmac account that was also my apple ID. I was looking forward to using the .Mac email address again. There is a setting that asks if you want a .me alias or something. Please do not push it. I received one email from the .Mac address after I pressed that thinking it was an alias I could no longer use .Mac again. I personally won't use .me and would have loved a warning stating that the .Mac address will become disfunctional. Now if I send an email to that email@example.com address it states user unknown. Please be warned and if anyone has a way to get a .Mac address back please let me know.
