Can One Get 5x CSP Points for New Phone By Purchasing Through T-Mobile?

The title sort of covers it. If one buys a new iPhone through T-Mobile and pays the T-Mobile bill with one of the Chase business cards that offers 5x points on cell phone service, can one get 5x points for a new iPhone this way? The Google says that one will get the 5 points/dollar, the Chase says no depending on how it's coded.

Didn't know if anyone has any experience with it here. I suppose buying through T-Mobile (instead of Apple) wouldn't hurt to try, I'm not losing anything by buying through T-Mobile. 

Curious to know of any thoughts/experiences with this, or how to earn bonus points when purchasing a new mobile phone.
