Hello, I have bought the newest iPod touch; the one with mailer, weather, and stock etc already. I upgraded iPod touch to firmware v1.4 using iTunes. Then I have tried to downgrade to firmware v1.1 to jailbreak. But I couldn't downgrade to firmware v1.1. I followed the instruction on some websites rightly. How should I jailbreak with firmware v1.4? Please give me some advices. Thank you.
