Suggested phone

I've bought an iPhone 3G, an iPhone 4, and an iPhone 5s, all from O2. You would think that they have a pretty good idea of what phone I'm likely to want next…

So when I went in to the O2 app on my iPhone to see what sort of upgrade options, I was suprised to see their suggestion that I would want to upgrade my iPhone 5S to… An iPhone 5s.
