Most iPhones except newest have problems with 8
I have an iPhone 4S - although it is the lowest of the phones that will run it - it reportedly runs 2x slower. I am not willing to cripple my phone, and I don't plan on buying a new one for a while (years). If it were to run well on 4, and 4S the upgrade rate would probably be MUCH higher. Apple is the author of the slower uptake....
