What can you tell me about the Sprint family of brands?

"The Sprint family of brands provides a lot of options for consumers. There's the Sprint parent brand, which operates traditionally. There's also Boost Mobile, which provides a pre-paid option for consumers, and Virgin Mobile, which provides more flexible, simple, open-ended plans with no contracts. No matter what kind of relationship consumers are looking for with their telecommunications provider, Sprint has made it possible for them to find what they're looking for."
