So the lasted iOS seed wanted to upgrade my @me.com address to iCloud which I'm fine with, I prefer it in fact. However, I can't send from a email@example.com address. When I sign into iCloud.com/AppleID Managment/Mountain Lion/iTunes, my firstname.lastname@example.org address reverts to my old email@example.com address. In which case, what is the point in this icloud alias? I would like to send mail from the icloud domain instead of me.com. Anyone got it working?
