Still using my iphone 3GS. I’ll be skipping a lot of numbers when I finally upgrade.
I'm currently using an iPhone 5s. No contract smart phone, from TracFone bought at Target. Cost me $199 a year ago, and I buy minutes once a year (over the last decade), cost is about $9 per month. I'm hoping they drop the cost of newer iPhone models on TracFone service, I notice the iPhone 6 is $288 from TracFone now. I can wait a while before getting the iPhone 8 or X. Advantage of TracFone is no contract and cheap to use.
