Checking with our Exchange guys right now. Initial question indicates that they run a PowerShell command to get that info. Once I find out what they query on I'll let you know.

*EDIT*
Looks like we at least are polling for Deviceuseragent and Devicetype. I don't know exactly what those correspond to 'inside' the TP2 but if you wanna freak them out boot up XDAndroid and connect. I don't know how to 'fake' those on the TP2...anyone else?
