    I am running Vista and I am running blackra1n in XP compatibility mode but every time I click on make it rain my phone just reboots into recover mode and does nothing else and i have to restore it in Itunes. can anyone help me? I have tried RC1 and RC3 but i get the same every time I have also tried Jailbreaking it from my wife’s XP PC and I still get the same. I have got a 1st gen G3 not the new one with the video on it. any help would be appreciated oh and I am running firmware 3.1.2
