That's a great phone, but I'd like to be able to share my iCloud data between all my devices.
I'd be happy with a 5s again, but can't stand to spend the same amount of money on last year's 5s if a new model comes out in 1-2 months. My wife offered to take her old 4s back and give me her new 5s, which I thought was sweet but I declined. It's crazy that I even brought the old phone with us on the trip, but it came in handy.
When we get back home in a few days I'm going to get a new battery for the spare iPhone 4s that I'm using now, and use it for a couple of months until the iPhone 6 comes out. Tonight the battery level dropped from 100% to 30% in just 5 hours, which is not unusual for a 3 year old phone.
I just can't believe the rear power hatch folded up the old phone like a sammich.
