Anyone has a complete spec of iPhone 6 model NG4W2LL/A ?

Hi all,

I replaced my faulty iPhone 6 (Space gray, 64GB, T-Mobile, model:MG5A2LL/A) this afternoon, because the glass display isn't fitting well with the phone's body. The genius rep told me that the store have the replacement to my iPhone model in stock.

When I got home this evening, I noticed that the replacement phone has a different model number (NG4W2LL/A). I googled this model number and found nothing.

I am wondering if anyone has the complete spec of this particular model. I want to compare this particular model to the t-mobile iphone I originally purchased. I am especially worried that this phone won't work with Verizon, as there is a possibility that I am switching to Verizon (CDMA) soon. Thanks!
