I bought an iPhone in the UK so it has FW 1.1.2. It has not been activated via iTunes/O2. I am trying to activate and Jailbreak the thing but keep coming across a number of problems. I have tried Conceited Software approach but I just cannot seems to kick the phone out of DFU mode once I have downgraded to 1.1.1. I double click the JAR file and it just says Rebooting Sending Commands and nothing actually happens. I tried using the Windows.bat file too (under Windows of course) and it just opens and closes in a millisecond. Can anyone explain what I am doing wrong?
