I have a Lumia 920 and the account I've been using with it has started to get flooded with spam mail. I've created a new account but before I switch the phone over to use it I'd like to make sure there's a way to restore/transfer my SMS messages. Is there a way to do this? The only WP8 app I've found that claims to backup/restore/transfer SMS messages is the Nokia app and that appears to only work over Bluetooth to another phone. Any thoughts would be appreciated!
