How do I correct my iCloud email address?
My iCloud account information contains an incorrect address: apparently when I was setting something up and was prompted for my email address, I gave my pobox.com address, thinking that it would be used as my "Reply-to" address. However, iCloud accepted it, "carved it in stone", and now I can't send email or alter the address, which is uneditable in Settings > Mail etc. > iCloud > Advanced Mail > iCloud Account Information / Address.
I've seen some threads that suggest that this can only be corrected by first deleting my current iCloud account. Is there a less drastic solution?
iPhone 4S, iOS 5.0.1
