you do not use it instead of wiping. you use the superwipe in addition to wiping. it just a way to make sure that the phone is clean for the new rom to be flashed into. it just takes a sec and does not hurt. never had any issues because of it. so why fix something that is not broke i guess.
Ah, OK, thanks!
Last question, for now... HTCdev mentioned this, as my last step in unlocking, and I did not do it. Do I need to worry about it anymore?
Code:
fastboot oem lock
