I am on tMobile. My 1st gen iphone is running 2.0, doesn't say in iTunes 2.0.1 or 2.0.2, just 2.0. I want to unlock and jailbreak the iphone with Pwnage Tool 2.0.2. Do I let it iTunes install the 2.0.2 software? Also Pwnage Tool 2.0.2 is not finding my iPhone1,1_2.0.1_5B108_Restore.ipsw firmware ?? Can I just download the iPhone1,1_2.0.1_5B108_Restore.ipsw from a website and then browse in Pwnage Tool 2.0.2??
