1) the biggest difference is with a subsidy your monthly payment stayed the same after 2 years. The carriers made out better. They have to change their model b.c people are jumping ship to tmobile/prepaid.
2) they still do shared plans it is just more data at a lower price. I don't think they have stopped subsidized yet. They have the next program, which is similar to financing but still more expensive.
Going to retract some of my statements about AT&T b/c I honestly did not notice their GoPhone plans.
for a subsidy at&t sends a check to apple or samsung for each phone sold. with the new plans its done by a financing company
it frees up a lot of cash for the carriers to upgrade their network instead of sending it to the phone manufacturer
I guess a better question would have been (since I am not currently financing my phone), how does T-Mobile provide you with your iPhone if you choose to finance it. Do they 1) give it to you from their inventory or 2) finance it when you purchase it from Apple (similarly do they just buy it from Apple when you apply for financing?).
I assumed they carry some iPhone stock, and in order to do that, they must pay Apple something, i.e. the same price as a subsidy. But if they don't carry their own stock, then my question about subsidies vs financing is moot.
