+1 for W7.

There are some settings particularly set for sprint once your press ##778# and click on view once that comes up click on view info and go to CDMA settings, and modem settings are the ones that probably need configuration. This will need a tech or if you have a friend that has a TP from sprint you can edit yourself. Once you edit everything than you can call sprint again and I can assure you that they will be able to communicate with your phone. You can edit all this info using the MSL grabber which will give you he code uniquely for your phone.
