Unable to merge contact lists on iPhone
When I first got my iPhone I didn't know what I was doing, and my contact list was called SDC. It's not an iCloud acct, it was an old POP email account, but it is now a MS Exchange email account.
Now that I am using iCould to sync everything, I can't find any way to send over the SDC contacts list to my Mac.
What I really want is to merge them all into my iCloud contacts list, so every thing will be synced automatically.
Can anyone tell me how I can efficiently export or merge a contact list not on iCloud?
p.s. Because that email account is now an exchange instead of a POP , I cannot seem to renter it for Apple's Mail account (which I had to redownload as I deleted it once I switched to MS Exchange.
