I have a few questions that need to be answered first. A. Do i need to downgrade to 2.0.1 to root? B. Can i upgrade to 2.2 once the phone has been rooted? C. Will i need any kernels or anything to overclock the phone or will SetCPU do that for me? D. Can i un-root at any time back to 2.1? (In case the official 2.2 comes out soon) Any help would be apreciated!
