Shit, piss and corruption. Got all the way through and recboot doesn't want to seem to work. I installed, .net 4.0, it launches fine, but when I press "Exit Recovery Mode" it doesn't seem to do anything. All that is displayed on my phone is the itunes and usb cable icon and when I launch itunes it wan't to recover and update.
Wait, hold on, perhaps recboot just takes 5 minutes to do it's thing. The iphone screen just went blank, not sure what to do now...
Ugh, doesn't seem to have done anything. Turned the phone on, still get the stupid "plug me into itunes" display.
