If your phone is rooted you can edit the build.prop file found in /system/build.prop and your phone will tether with noproblem bypassing metroPCS block Wireless or USB!
Open build.prop with in a text editor by long pressing the file until a menu comes up.
Scroll to the bottom of the file and look for ....
ro.tether.denied=true <-- Change to false save and exit.
*Your Phone will have to be rooted to edit this file.
This is only one way of many to manipulate your phone to work the way you want it to.
