No iPhone 6 Or iPhone 6 Plus For Virgin Mobile USA!

I don't get why Virgin Mobile USA does not have the iPhone 6 or the 6 Plus. Last time when the iPhone 5s and the 5c came out. Virgin Mobile USA got them very quickly. Virgin Mobile USA got the iPhone 5s and the 5c about a couple of months after their official announcement by Apple.
Now, Apple announced the iPhone 6 and 6 Plus last September and still Virgin Mobile USA does not have it.
Here is the thing. Virgin Mobile USA is owned by Sprint and runs off the Sprint network. Boost Mobile is also a pre paid cell phone company like Virgin Mobile USA and is also owned by Sprint.
This is where it gets a little frustrating for me. Boost Mobile now sells the iPhone 6 and 6 Plus and yet Virgin Mobile USA does not.
As of this writing, there is still no word as to if Virgin Mobile USA will get the iPhone 6 or the 6 Plus.
