I got an email that I need to upgrade to iCloud 4.1, but it appears that I already have iCloud 4.1. Are these updates that I need to install to this version, or do I just ignore and is 4.1, 4.1 no matter what? I am just confused whether this is upgraded from what I already have and why I got this email. Thank you.
