My step mother just bought an iphone 6 plus and it is being shipped directly to my house. She will be joining me for Thanksgiving (different state) and wanted it all setup for her when she arrives. However, she still needs to use her own flip phone until then. Is there a way to pre-configure the iphone without activating so she does not loose her flip phone service before she arrives? I was just trying to get a head start on downloading/setup all the apps she needs.
