Can i trade in my s4 for a iphone 5s?

I like my s4 but i want to try something new, like the iphone 5s, people say it an awesome phone, so I just want to try it out but I can't afford to buy another phone and I don't want my s4 to go to waste, so is it possible that I can trade my phone for a apple product and if I can how would I do it, my phone company is tmobile.

T mobile will only give you $100-$200 tops for the used s4 so your best option is to stick with the s4 besides the iPhone has hardly any customization to it and you can't control it as much as android phones.

As it is used you can't trade your phone but if you have a little cash you could sell it in ebay (you will get the best price for your phone here) and buy the iPhone. Personally I'd stick with the S4 as iPhone isn't really that great. I'm not saying its bad but there's no customisation and it's fairly simple and a bit boring, although you may like this

Only apple fanboys/girls say it's an awesome phone, everyone else says (knows) it's a disappointment. If you want something different be truly different. Not like every other iphone owner. Go to windows, or an advanced android, such as Huawei or zopo (they use something called aliyun which is a heavily modded android)
