I'm sure a lot of you have heard of issues about redsn0w freezing at waiting for reboot, or it says done but iphone went blank and didn't respond to jailbreak? Personally I have that problem too, it didn't work in my xp in normal mode but it did work in safe mode (compatibility mode if you like).

So what's the deal, and why has this happened? What's the reason behind all this extra work that some of us need to do in order to jailbreak an iPhone?
