First question: Did you ever plug the phone into your PC PRIOR to running
the software? If so, go into Device Manager and then remove the Motorola USB
Modem wherever it appears (look at Modems, Ports, USB). Then Reboot, Then
run MPT and only plug in the phone when prompted. Use the original Motorola
USB cable if possible. Most others will work but not all (I know this from
experience).
I don't know if Sprint crippled the phone the way Verizon did but look at
www.howardforums.com and www.motox.info for more details.
