There are a select few 3.0s that have 1 GB capacity, but not all do. The 3.1s that have been released are all gig capable. And that's the exact one I just picked up, but refurbed from Amazon. I haven't been able to set it up yet because suddenlink hasn't made it out to our new place yet. I'll have a better idea of how good it is after this week, but not it's full capabilities, as I only purchased the 400 plan from suddenlink. I have no need yet for the 1 gig plan until my work ups our VPN server connection, so until then I'm capped by the VPN. And we don't push that capacity with our other devices at home.
