I have a VZW 8703e that I would like to put on the Sprint network. I've taken care of the ESN problem, but what I'm wondering is if I will still need to flash the firmware or OS to the Sprint software, and if so, if this is possible. Any suggestions?

Thanks for the help!

have you gone any further w/ your activation? i have a VZW phone that i would like to put on my Sprint acct...

You had better talk to Sprint first. Typically they will not put a non-Sprint phone on their network - flashed or not. Its the PIN and ESN that tells the difference. Verizon is the same way.

if you have taken care of esn problem they should if you can get threw to tech support and someone who knows what they are doing it should go threw

Which OS is on the device makes no difference. OS's are interchangeable between like devices of different carriers. The ESN issue your only issue.
