the stock 0.37.0000 locker and 0.37.comex unlocker can be found
www.forum.ppcgeeks.com/showthread.php?t=61333 and the 0.40.0000 locker is inside the 9/25 update rom from
http://www.member.america.htc.com/do...2.01.651.6.exe and can be unlocked with .37.comex but you have to reflash sprint rom to lock it again. if you unlock your device and flash a custom rom, reflashing this stock rom will relock 9 out of 10 times. put your device in bootloader after flash and auto customize completes and check to see if it locked, flash again if it don't and check, if you ever need to return your device to sprint.
