[Sprint] Will my Boost account get messed up from Sprint with an unpaid balance?

http://androidforums.com – I had someone flash my Sprint Evo over to Boost Mobile and the guy also had my Sprint number ported too. So I am currently using an Evo with Boost and I won't be able to pay off my Sprint account anytime soon. Will this mess up my Boost account if my Sprint account goes into collections? The Sprint account had 3 phone lines and it's not in my name. (General)
