BBC on Orbit - noob questions

Hi All,

Sorry if this sounds a bit dim, or is on the wrong part of the forum (please move is required), but I'm new to Blackberry and need some guidance.

I'm trying to get BlackBerry Connect installed on my HTC Orbit running Windows Mobile 6.1 (done), connected to the network (done) and synched with my Blackberry Service (pending) and need your help to understand the implications of what I'm aobut to do:

When I enter my account details on my HTC Orbit and connect it you my companys Blackberry service, will I invalidate my proper Blackberry handheld device and knock it off the network ?

Can I operate both handhelds simultaneously, or is it one or the other only ?

Can corporate Blackberry and private Outlook email accounts (push or pop) co-exist on a single WM6 device ?

respectfully,

nid
