You can not "reprogram" a PIN. The PIN is hardware dependant and is part of the device itself.
If you get a 7100t, you must first get it unlocked by T-Mobile US. If you are using a BES, you can put in your existing SIM card, and change the pin on the BES.
If you are using BWC, it is much more difficult, since T-Mobile US must first release the PIN/IMEI numbers from their databases (which may require getting RIM involved) so that you can register the 7100t on your provider's BWC web site.
