(adsbygoogle = window.adsbygoogle || []).push({}); I have a iphone 3g that I want to jailbreak, but every time I try running greenpoison it says to try again after I follow the on-screen instructions, like hold for 10 seconds, etc. Anyone else have this problem or know how to fix it?

I had this same problem you have to use redsn0w with correct firmware and you should be fine
