We are a little late on reporting this one, as it got lost in the DROID Incredible melee that happened yesterday afternoon, however the Sprint EVO 4G — running Android 2.2 — has been rooted. The good people over at xda-developers have the write-up ready to go, although there is this warning:
My advice would just be to READ very carefully
through all the STEPS. It’s very easy to get confused if
your are just excited about it and are
trying to finish as soon as possible.
You’ve been warned! If you need the “roots” give the tutorial a shot. Enjoy!
