So I used pwnageTool 4.01 and the guide on redmonpie.com. After I had jailbroken OS 4.0, I restored all my contacts etc and it reverted me to apple-certified 4.0 . Is there any way to get back to a jailbroken phone? My guess is that i jailbroke it on my mac then used my PC since that's the computer that's sync'd with my phone that i screwed it up? Any advice?
