Switching the Storm 9530 to Sprint.

[ShadowWolfX4]

I know that you can use a BlackBerry Storm 9530 on Sprint. A friend of mine has done so but had someone do it for him and lost contact with his unlocker over time. At any rate, I want to know this. Do you clone an ESN from another "doner" phone as I don't mind putting 20$ down to do so, or is there a way to mimick the ESN of some other phone temporarily. Sprint is eager to help me and told me to flash the phone to work on their network and said if there was any way that they could help, they'd do it at no fee. They want to keep me happy so they are more then willing to cooperate. I have found that all services of the BlackBerry Storm 9530 will work on Sprint no problem. After speaking with a rep from BlackBerry and Sprint, I found it is totally possible to do this. Again, this CAN be done. Please help?

Summery: I need to flash a BlackBerry 9530 to work on Sprint. It -CAN- be done. So how do I do it?
