Can I buy an iPhone through T-mobile and use a prepaid T-mobile plan?

So I was looking at the prepaid section of tmobiles site http://prepaid-phones.t-mobile.com/prepaid-plans and I saw a plan for 30$ a month 5gb data, 100 mins talk and unlimited text. This sounded like a really good deal, but when I went click "Shop phones" underneath "Get started", there were no iPhones listed. But when I click "bring your own device" it says I can use iPhones

I don't have an iPhone yet, so I couldn't use the bring your own thing. So is it possible to do the t-mobile thing where you get the phone, but make like a monthly payment to pay off the phone, but still get the 30$ a month plan I was looking at?
