Developers have managed to work on a Bash Script that will ensure the entire SIM unlocking process is fully automated – so that there is no need to dive into fancy calculations and what not. Bear in mind that this particular root exploit only works for those who already own a rooted HTC One S. As for folks who do not want to root their HTC One S device, you can always wait for T-Mobile (as well as the majority of other service providers) to unlock your handset after you carry the One S around for 90 days.
