Hi All, I keep up to date on my device iPhone 4 and have all my SHSH's backed up but a friend is trying to Jailbreak his iPhone 3G which is on 4.1. Whats the easiest way please? he doesnt need an unlock. I have been researching this for him but a bit confused. I previously used the Jailbreakme website to do his phone on 3.1.2 but he has upgraded since then. Some advice please?
