Firstly, a quick warning. I had a iPhone4 with ios4.01 that I had done the jailbreak on. I had vWallpaper installed. Last night I attempted to download what appeared to be a new wallpaper through their app. It caused my phone to completely freeze upon reboot. I could unlock it, but nothing else would open. I couldn't even access SBSettings to allow me to SSH into the phone, and try to fix it. Of course I had to restore the phone, but sneaky-ass Apple made me upgrade to 4.02. So, the question is whether it's possible to break 4.02 yet. I know the Jailbreakme.com exploit won't work. What about Limera1n? Questions, comments, hubris, and hyperbole are welcome.
