I think the rest of the UK is different. iPhone ownership goes hand in hand with a certain level of disposable income and fashion sensitivity. Androids dominate the lower end of the smartphone market, but people commuting by tube are not in that bracket. People who live in London and commute by tube automatically fall into an above-average income bracket. In my experience they're far more likely to have the disposable income to get an iPhone over a cheaper smartphone.
