Be aware if you get a replacement phone, it's a refurbished. And could well be faulty.
my phone was replaced before traveling, within 48 hours. The screen was acting up, while I was 5000 miles away.
Was stuck with it all my trip! Spoke to the manager about it. They cared less...
When I pay $1050 for a phone, I expect service and replacement units that work. And are checked by Apple before given to the user.
