It's weird... The phone is still mine but my company pays for it now. And will pay for a new one - but i get to keep it if I leave...
I love this company.. For real - they take care of us...
I "think" our setup is sorta similar. It's an employees phone, and employees pay the bill (reimbursed), but IT will set it up and support it. I'll check with IT and see how it's done.
But I do know it has to be a BlackBerry and I think they request you go with Verizon.
