I discovered that when my device was plugged in to my desktop one day with Wireless swicted off and I was still getting emails on it....freaked me out for like 10 minutes until I figured it out!!! So the fact that your device is getting emails when plugged in but not wirelessly tells me there's something wrong in your setup. Need some more info on this one I think but start by looking at your firewall and have another think about the whole BES on Exchange thing. Most people here won't be running BES on Exchange so might be a tough one to dig through. Check your event logs and the BES logs if the event logs don't help you out.
you are correct that a user can send and receive email while he is wired and has wireless turned off but the user has to be activated on the BES first, but you are wrong in thinking that the user can be activated on the BES through the wire if they dont have a BB data plan.
a blackberry cannot be activated on a BES if there is no bb dataplan
