Do you have separate iCloud accounts? Keychain syncing kills me...

Definitely dry-run. I didn't do that and it was a huge pain to recover everything.

I was hoping to have to setup a whole new apple account for it. I'm normally Android, but cage across a cheap second hand iphone at an auction - but my daughter wanted it, so it never happened.

It would be easier for me to just go Android, and I do have spare older devices now too.
