I'm moving from a 5 to a 6. Normally I do a full backup - old iPhone transfers apps to computer etc. Then restore - all apps are restored with data from old phone (such as viber/whatsapp messages, app information, game saves etc). With this app thinning "upgrade" in iOS9 - how do I restore app data ? I just did a backup and restore but my new phone was downloading the app from app store rather than laptop....presumably without the app data ?! Any help on this much appreciated.
