Help me with the storm

Ok, so ive been wanting to get my storm unlocked but i have a problem. I bought this phone about 4 months ago and about a month ago or so i decided to change it. ok so now im going to mexico and im going to leave my new phone here and take the storm over there. but the the account is under a company name since my boss gave it to me. how can i get the unlock code for my phone??? thanks!
