While I am shocked at this sort of security risk on a bn, I wonder how you use it to access your files without, as you say, using ActiveSync? I am on a public network at school and am therefore rather worried about this (then again, I doubt anyone on campus knows what telnet is, let alone how to isolate my machine). Please email hw with the details of this as soon as possible so they can see that, even if they meant to do it, it is of concern to users. If you can tell me how to do this and I can confirm it, I will also email them. I do not doubt your findings, I just would like to provide details of my setup so that hw can see that these are two independent use cases.
