Virgin Mobile getting rid of grandfathered plan options with new smartphone purchases?

A new text message is currently being sent out to Virgin Mobile USA customers with what may be an in important announcement if you're looking towards picking up a new device from them anytime soon.

VMFreeMsg Starting 5/27/12, new smartphones will be subject to current plan rates. This will apply if you switch phones. Go to for info.

At first glance, it may appear as though Virgin Mobile might be releasing some new smartphone plans, but that's not the case. When you visit the link they're advising folks that anytime you upgrade now you're required to pick from one of the already existing plans available. This looks to imply that if you're on grandfathered plan, they'll no longer allow you to keep it when upgrading to a new device. Anyone else on Virgin Mobile get this message or any further clarification in it?

Thanks, Brian!
