So let me get this straight, does Sprint have 4G LTE now?

So Sprint is launching a bunch of phones right now (ex: Galaxy Nexus, EVO 4G LTE, etc.) touting that they can connect to their new 4G LTE network. I've heard that Sprint, as of now, does NOT currently have an LTE network deployed. Is this true? If so, does anyone know when it'll be launching? Why launch phones now if they can't even connect and are essentially 3G phones?
