I found a much easier and simpler way to reveal the carrier SPC/MSL code on just about any HTC Android phone. (i have used it personally on a HERO, ERIS and EVO) Go to a file sharing site like 4shared or filecrop.com and simply search for the file keywords "msl apk" . The results will list a little app called MSL.APK that you canet download from the file site and install on your HTC android. (phone must be rooted in order for this to work!) and when you click "FIND MSL" wHOLAA!! YOU GOT YOUR SPC'/MSL and you may use Workshop or QPST to read phone and write the 0's to default spc.
