To some extent I can understand you are voting with your wallet by not contributing to a design you wouldn't be happy with but you already did for the 3.5" screen. All the time, you are using a 3.5" screen as your reference point for daily usage and saying it's far too small. That's why they made a 4" one. If you want a 4.7" then of course 3.5" is too small but 4" is almost half way there so doesn't it make sense to at least move a little closer to the goal? If it was a case where a lot of people were doing the same thing then sure, it might make them think twice but they're selling more premium phones than anyone else so you're only making yourself suffer for years. People who complain about Apple's options are a bit like self-immolating protestors, i.e if they don't do what I want, I'll just sit here and suffer and that'll show 'em. If it's the right thing to do, they'll do it anyway.
Let's say that we get to September and they end up making another sub-4.5" phone. You can be assured that will be the case in 2015 too so that means 2016 before the possibility rolls round again. Is the next move Android, stick to 3.5" until it breaks or just go with the next one they offer in September?
