Scott - you're absolutely correct - brain-fart on my part

In fact, I was at a Starbucks the other day which shares its parking lot with a Sprint store. I parked right in front of the Sprint entrance doors, and I noticed a Virgin Mobile logo displayed right on the door.

Also, for decaf, confirming that with Virgin, you do not need a subscription - you buy what you need. As pointed out by others above, there is no rollover for any unused data. I bought a Virgin stick to use when I go to visit my mom, who does not have high-speed in her home.
