Can you buy an iphone 5 from apple to get it on Virgin Mobile?

If I buy an iPhone at the Apple Store or online (Virgin doesn't have the iphone 5 yet), can I take to a Sprint Store (Sprint owns Virgin Mobile) to get it activated on Virgin's network?

Nope. You only can use the iphone 4 or 4s and it has to be the iphone 4 or 4s from Virgin Mobile. Virgin Mobile does not allow you to bring your iphone from another cell phone carriers to them.
