Just so everyone knows. If you inadvertently update your phone with today's OTA update and lose the latest root exploit, there is a way back.
Just run the ORIGINAL .5 RUU that came out last month and then you will be able to root using yesterday's exploit.
This works for now, but beware of any future update/RUU from Sprint.
anyone have this file they can upload? sprint has the new one on the site and I deleted it from my computer. the good news is I have not updated, and turned off auto update just now. but it would be nice to have the file when I need it
