I've been wanting to do this for a while, but haven't been able to because I'm worried I'll lose my text history. I'm wondering if I can "Setup as new phone" but bring over all my text/iMessage history.
The closest way I can think of to do that is to uninstall all third party apps, delete anything else in your first-party apps, and reset all settings. Then, backup your phone, do a clean restore and restore your backup back onto your phone...
It says it can "transfer SMS messages with attachments between iOS 6 and iOS 7." I tried it several times on my 5s back in the days of iOS 7.0.0 and it failed with error messages about a corrupt backup. I tried importing messages into a clean backup (like suggested in the above url) and I tried deleting some data from a full backup.
Always been interested in this idea myself. I think the best thing to do is to use one of these 3rd party applications to export your text messages in as PDF or something and just set your phone up as new.
