    Was wondering if anyone had a good tutorial on downgrading the OS to make the phone run smooth? My previous phone broke and I need this to hold me over.

    but you should find your answer on YouTube.

    What i did is that i installed iOS 3.1.3 into my iPhone 3G, and kicked it out of DFU mode with an app called 'tinyumbrella'
