Im considering rooting my stock HTC desire (froyo etc) but only for reasons that i can install apps as system like Wavesecure etc. Ive got no interest playing with custom roms etc. A few questions i cant get definitive answers to: (i) is the rooting JUST going to give me SU access rights or is it going to wipe my current stock rom, HTC sense and so on? I want to keep my current room intact and just have SU access on top of that (ii) Do i need a complete factory reset after doing so or will i lose everything currently installed by doing so? (iii) Is it going to affect things like marketplace availability, future ROM OTA updates arriving and so on? (iv) I assume its easy to undo the rooting without lasting issues? Is unrevoked via SLAX boot the way to go with this? Help with these appreciated!
