The UnrEVOked Root can be done and keep you unit "Stock"...I have not done anything else to mine yet other than that, as I am still afraid of bricking (I have never flashed a custom rom or rooted the other way before)...All that has to be done is uninstall Unrevoked and you are back to normal...And the wifi tether works :P
In fact...I am on the tether now
