I just switched from Sprint to T-mobile. I financed my T-mobile 5S through the Apple store, then activated a T-mobile SIM card online, and got the $30 per month deal for 5GB 4g data and 100 minutes per month, with 10 cents per minute beyond that (prepaid). $30 per month is by far the least I've ever paid for an iPhone.
