I'm guessing it will work if you ahd a previous phone that worked. My understanding is Sprint phones are not locked. You may need to have your tech guys put all the right configurations on it though for it to work.
Just flash one of the ROMS with no carrier provisioning, or a generic ROM that isn't tied to any specific carrier.
By the way, the software used to provision phones for another network is totally legit and legal. not sure why someone else said they couldn't mention it here but I will. It's called houdinisoft and you can get it from:
http://www.houdinisoft.com/
But I don't know if your carrier is one of the ones built into it or not. So you might have to manually enter settings and such. But the software should walk you through it and you can get the settings from your carrier's support. Maybe email houdinisoft and ask them if it will work for you first...
