as i am by no means an expert on “rooting” your device, i’ll have to defer to those who run in those circles for confirmation on this, but to my knowledge you can return back to your stock 2.0.1 before this week’s ota update for 2.1 comes across.
the sholes crew has released their latest SMUpdater which is now on v6, is available in the market for $5 and apparently can do the trick.
if you run into issues with the sholes app, you can check out this post at the droid forums which will walk you through unrooting step-by-step.
for those of you that have completed this task, i’d love to hear details and tips for the rest of our readers. thanks.
