Mine is cellular, but no carrier. That's how it is in Australia when buying from Apple. We just pop a SIM in & off we go. We have the option of buying the iPad from a carrier too though. So, I was wondering, for those of you in the US, ordering cellular iPads, does that mean that they come with the SIM already installed out of the box? I'm just curious since it seems that different carriers seem to be different delivery times for you. While, for us in AU, it was just the model that determined the wait time since the carrier doesn't factor in.
