i need to jailbreak my iPhone so that I can run Circuitous on it, because my home button is broken due to water damage and I need an alternative (Circuitous does the trick). recently however I updated to iOS4.0 by accident and I'm having trouble downgrading. can anyone help me out on the exact process? because when I try to downgrade to 3.1.3 it says "the iPhone is not eligible for this build".
thanks in advance
