Silver or Space Gray iPhone 6S?

Should I get a silver or space gray iPhone 6s. I'm a 17 year old girl if that matters. And this is the case I'm going to get: Silver or Space Gray iPhone 6S - 1

Would the case look better with a silver or space gray phone?

Can I put T-Mobile nano sim in iPhone 6 that was used for sprint?

Hi, I decided to already try this. The person who was using the 6 got a 6S from sprint and is already using service on it. I took the nano sim out of my iPhone 5 and put it in the 6. It took a minute for it to load, but then the upper left corner said LTE and then finally, it loaded the Wi-Fi bars and service dots/ said T-Mobile. I texted someone from it and then we re able to respond.

Is there anything I should be worried about not working? Is this considered "unlocked"? IIm worried that there are a couple features that might not work or something.
