I think you're discounting (ha) the allure of free/cheap to people who don't have disposable income. Which is to say, most people.
People in the US are willing to spend extra on the Apple phone. There's already drama over the stupid blue text/green text thing, imagine a world where you know that your social interactions with a Facebook user are snooped on. I think it could lead to some significant ostracization. Private party -- no Facebookers.
I don't think iPhones signal much (in the US at least) -- they have like 50% market share here.
Thinking about it, those diamond-lacking iPhones look quite shabby, already!
Laziness, apathy and network effects are perhaps equally powerful forces. After all, I continue to use Google and Instagram despite my knowing how the sausage is made there.
That's not true. That's why credit exists. Selling poor people shit they can't afford with terrible terms is a long-standing American tradition.
When a debtor is unable to pay (often times through no fault of their own), the creditor eats the cost because their margins are good enough to allow for it. That effectively represents a wealth transfer between corporations providing the services and the corporations providing the credit.
Obviously this happens with mortgages, cars, and other extremely high value things. IRS debts, student loan debts...
But what about credit cards? Don't they have mechanisms other than tanking your credit report? And if not, why don't poor indebted people simply default all the time to remove debt?
