Ok I got a few questions: 1. Ok on Wiigator's blog on this site he says all you have to do is run the miospatcher and then install the backup launcher. Is gamma needed? What about a cIOS is that also needed? 2. Can I run/install the backup launcher on a 4.0 with no problems/conflicts? 3. And can it hurt your DVD drive like play movies via the DVD drive can? Thanks in advance!
