They just started not having crappy phones in June, so it will take some time for perceptions to change. Heck I have a virgin mobile phone and this is the first I have heard of it(iPhone any way, in June they announced getting the EVO 3d with android 4 on it).

Didn't you read the part about them not being marketed and the iPhone not even being available until a few months ago?

To be fair Virgin started throttling after a couple gigabytes a few months ago, but the throttled speeds are still supposed to be relatively fast (256 kilobit).
