Somewhere along the way with my PC, I accidentally established two separate i Tunes accounts – one with my user name, and one with that same user name followed by an email address.
Songs have been purchased under both user names and those songs are all on the PC.
If you have content from more than one i Tunes Store account stored in a given i Tunes library, then you simply need to make sure that you’ve authorized your computer for each of the accounts that contains protected content you wish to use.
Because this is done entirely on the i OS device, there is no longer any need to have to sync back to i Cloud, i Tunes, or a computer for the change to take effect, instead you make the change once directly on the i Phone, and thanks to i Cloud, it will propagate automatically to other i OS and OS X devices that use the same Apple ID. In the example screenshots, the address information for multiple “Santa” and “Santa Claus” has been merged into a single card.
The first contact edited will be the one that accepts the merged details: Next, simply find and “Link” the additional contact cards, whether they are duplicates, triplicates, alternate address information, or whatever else: Once you choose “Done”, there will only be a single contact for the details you merged (linked), in this example it’s “Santa Claus”.
Then rename the merged database file (the left one) to “msgstore.db”, copy it to the sdcard to location /sdcard/Whats App/Databases/and make sure that it`s the only file in that folder.
Now install Whatsapp and confirm when asked to import the Backup during installation.
