I bought a new iPhone and used iTunes to transfer all my data and settings from my old iPhone which worked great. ( I didn't used iCloud as I had read it was slow and didn't always transfer passwords etc.)
I now have both phones linked to my laptop (and each other somehow) so all my photos, emails etc go to both devices showing as "sue's iPhone" - nothing to differentiate them that I can see.
I want to wipe my old iPhone before giving it to my granddaughter and the instructions for wiping are telling me to remove the sim, sign out of iCloud and all apps before restoring factory settings. I'm sure it said to delete the iCloud account too?
What I'm worried about is how to make sure nothing changes on my new phone if I start deleting stuff on my old phone. I can't remember half my passwords or settings and don't want to mess it up - the fact that both phones seem to have the same icloud/itunes ID worries me. Any advice please?
