Upgrade / iCloud restore sans reset option?
I'm hoping there may be a knowledgeable fellow iPhone user that would be able to help me with my recent upgrade.
My upgrade was from an iPhone3 (3G) to an iPhone6 (4G).
When I recieved the iPhone6, it was not activated (no cellular network), but I connected it to the internet via WiFi and it seemed to update several things on the phone automatically, without input from me, including the following:
1) photo albums and photos were added from my iPad 2017,
2) contacts were added from my iPhone3
I am specifically interested in restoring SMS messages from the iPhone3, but without doing a reset & restore from iCloud on the iPhone6 -- I don't want to lose the contact information and photos that had already been automatically transferrred when I connected the phone via WiFi.
My iPhone6 is now activated, and the iPhone3 is deactivated. Before going into a local AT&T store to activate the iPhone6, I did a backup (to the iCloud) of the data associated with the iPhone3, so I am hoping that I can eventually get the iPhone6 in the same state (with all SMS and voicemail history) as the iPhone3 prior to switching.
Thank you in advance for any helpful suggestions on how to accomplish this without resetting my iPhone6!
