Delete or merging iCloud accounts
I activated an iCloud account with my gmail address years ago and wanted to change my e-mail address to an me.com/icloud.com one. The advice back then was to set up a new account. No I have both, but all my purchases of music, movies, tv shows and apps have been done on the gmail version, yet the e-mail address I use is an icloud.com one on the other account.
Is there a way to delete the icloud account and move the email address to my gmail one or merge the two accounts?
Many thanks.
